I was a complete newbie to writing HTML in the DOM, and I sort of used that style as the next step of advancement.
I couldn't remember the attribute and could not find it through search. I knew there was a one liner for inline style.
I was hoping to keep it the same, but I'll convert to your post example.
Thanks for the reminder!

Can you please use following:
var div = document.createElement('div');
div.setAttribute('style', 'width:330px; float:left');

Hi,
I'd like help to complete this script I'm working on. so for it works but I'm strugling to incorporate theremaining three conditions:
1-The same character may not appear more than twice in a row (Kabooom1)
2-Not more than two sequencial alphanumeric characters are permited (Ab123cym)
3-Black list some words like:(Mark, London)
Any help would be appreciated.script as below
=========================================
<script type="text/javascript">
function checkForm(form)
{
if(form.username.value == "") {
alert("Error: Username cannot be blank!");
form.username.focus();
return false;
}
re = /^\w+$/;
if(!re.test(form.username.value)) {
alert("Error: Username must contain only letters, numbers and underscores!");
form.username.focus();
return false;
}
re = /.{8}/;
if(form.pwd1.value != "" && form.pwd1.value == form.pwd2.value)
if(!re.test(form.pwd1.value)) {
alert("Error: Password must contain eight characters Only, Try again!");
form.pwd1.focus();
return false;
}
if(form.pwd1.value !== "" && form.pwd1.value == form.pwd2.value) {
if(form.pwd1.value.length >= 9) {
alert("Error: Password must contain eight characters Only, Try again!");
form.pwd1.focus();
return false;
}
if(form.pwd1.value == form.username.value) {
alert("Error: Password must be different from Username!");
form.pwd1.focus();
return false;
}

The same character may not appear more than twice in a row (Kabooom1)
If it matches the regular expression /(\w)\1/, then you have repeated characters.
Not more than two sequential alphanumeric characters are permitted (Ab123cym)
Not easy with a regular expression. Try something like:
function limitSequentialCharacters(value, limit) {
var sequentialCount = 0;
var prevChar = value.charCodeAt(0);
for (var i = 1; i < value.length; i++) {
var char = value.charCodeAt(i);
if (char === prevChar + 1) {
sequentialCount++;
if (sequentialCount === limit) {
return false;
}
}
else {
sequentialCount = 0;
}
prevChar = char;
}
return true;
}
Blacklist some words like: (Mark, London)
You can either use a regular expression like /^Mark|London$/i, or check the input against a list of blacklisted words.

You really need to do this in server side code by calling a webservice. Client side validation can always be hacked.

Hi All
Can we use java-script/JQuery for interfacing with Hardware device API installed on client system.

No, that would break the security barrier between a browser and client system.

The answer is that it depends on what you are doing.
For instance if you are writing application or server side javascript (node.js[^]) then the answer is yes you can do this.
Another example is writing mobile applications written in HTML and javascript for mobile platforms. In this case you can use phonegap[^] which will give you access to certain hardware features of the device.
If you are purely doing web development with pages delivered from a server then the answer will be No (for now) as it violates the sandbox security put in place by the browser.

Also should have noted that it depends on the browser you are using...
I forgot that with Chrome you can do some stuff with the local hardware. An example is that I have some pinocc.io[^] boards and they are initially configured from a web page that uses chrome features. I have also read some articles in the past where a chrome browser access an arduino[^] via the local USB port.
More info on this feature of Chrome can be found... https://developer.chrome.com/apps/app_serial[^]

No. For security purposes browsers will not allow that. Use Java or ActiveX or some other technology that has to be installed on the client machine.

You can try using AJAX.
Create an ajax call to a php file with the following code:
getPage.php
<?php
function getPost( $name, $default ){
$value = $default;
if( isset( $_POST[ $name ] ) && $_POST[ $name ] != '' ) {
$value = $_POST[ $name ];
}
return $value;
}
function getSslPage($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$site = getPost( 'site', '' );
$content = 'empty';
$error = '';
$content = getSslPage( $site );
if( !$content ) {
$error = 'no file found';
}
$arr = array( 'error' => $error, 'htmlResult' => htmlspecialchars($content) );
echo json_encode($arr);
?>
in javascript:
var data = {};
data["site"] = 'http://www.example.com/';
$.ajax({
type: "POST",
url: 'getPage.php',
data: data,
dataType: 'json',
success: function( msg )
{
if( msg['error'] !== '' ) {
alert( 'there was an error: ' + msg['error'] );
}
else {
alert( ' html Found: ' + msg['htmlResult'] );
}
}
});

How to validate postdate?

You have to be much more specific to get any answers - it's just not a question despite the question-mark...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

You can validate date with split the date into some part.

I have a dropdown and multiple gridviews in the page .And on the basis of value selected from dropdown, data is loaded in Gridviews. And each gridview has linkbutton in each row, on click of which modal popup opens.
I want gridviews to be collapsed on dropdown select index change.
but my javascript function is not getting called.
And getElementByTagName('tr') is not working in internet explorer.
This is my Grid:
<asp:GridView ID="gvBillCalc" runat="server" AutoGenerateColumns="False" BorderColor="#CCCCCC"
BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Bold="True" GridLines="Vertical"
Font-Size="Small" EmptyDataText="No Data Found" Width="100%" OnRowDataBound="gvBillCalc_OnRowDataBound"
BackColor="WhiteSmoke">
<Columns>
<asp:TemplateField>
<HeaderStyle Width="25px" />
<ItemStyle Width="25px" BackColor="White" />
<HeaderTemplate>
<asp:Image ID="imgTab" onclick="javascript:Toggle();" runat="server" ImageUrl="../Images/plus.gif"
ToolTip="Expand" />
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Item Particular">
<ItemTemplate>
<asp:Label ID="lbDesc" Text='<%#Eval("desc")%>' runat="server"></asp:Label>
<asp:HiddenField ID="hdnID" runat="server" Value='<%#Eval("id") %>' />
</ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Amount(In Rs.)">
<ItemTemplate>
<asp:Label ID="lbAmt" Text='<%#Eval("total")%>' runat="server"></asp:Label></ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" HorizontalAlign="Right" />
</asp:TemplateField>
<asp:TemplateField HeaderText="View/Edit">

</ItemTemplate>

<ItemStyle Font-Size="12px" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Remarks">
<ItemTemplate>
<asp:Label ID="lbRemark" Text='<%#Eval("Remarks")%>' runat="server"></asp:Label></ItemTemplate>
<HeaderStyle Font-Size="14px" />
<ItemStyle Font-Size="12px" />
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066" />
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
<EmptyDataRowStyle BackColor="#FFC0C0" Font-Bold="True" Font-Size="X-Small" />
</asp:GridView>
This is my javascript:
var Grid = null;
var UpperBound = 0;
var LowerBound = 1;
var Grid1 = null;
var UpperBound1 = 0;
var LowerBound1 = 1;
var CollapseImage = '../Images/minus.gif';
var ExpandImage = '../Images/plus.gif';
var CollapseImage1 = '../Images/minus.gif';
var ExpandImage1 = '../Images/plus.gif';
var IsExpanded = true;
var IsExpanded1 = true;
var Rows = null;
var Rows1 = null;
var n = 1;
var n1 = 1;
var TimeSpan = 25;
var TimeSpan1 = 25;
window.onload = function () {
Grid = document.getElementById('<%= gvBillCalc.ClientID %>');
UpperBound = parseInt('<%= this.gvBillCalc.Rows.Count %>');
Rows = Grid.getElementsByTagName('tr');
}
function Toggle() {
debugger;
var Image = this;
ToggleImage(Image);
ToggleRows();
}
function ToggleImage(Image) {
if (IsExpanded) {
Image.src = ExpandImage;
Image.title = 'Expand';
Grid.rules = 'none';
n = LowerBound;
IsExpanded = false;
}
else {
Image.src = CollapseImage;
Image.title = 'Collapse';
Grid.rules = 'cols';
n = UpperBound;
IsExpanded = true;
}
}
function ToggleRows() {
if (n < LowerBound || n > UpperBound) return;
Rows[n].style.display = Rows[n].style.display == '' ? 'none' : '';
if (IsExpanded) n--; else n++;
setTimeout("ToggleRows()", TimeSpan);
}
This is Code Behind:
protected void ddlNodeName_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlNodeName.SelectedItem.Value != "0")
{
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "CallMyFunction", "Toggle();", true);
Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "Toggle()", true);
ClientScript.RegisterStartupScript(GetType(), "CallMyFunction", "Toggle();", true);
}
else
{
}
}

This[^] article has the sample on how you can use client side event. Also, it has sample on collapsing grid rows which might help you.

Hi
I am working on an existing project inherited from one of these fly by night digital media companies. They probably had some amazing deadline as usual that results in bad website construction.
The developer at the time thought it great to use RequireJS and load every script file used by the solution into the main aspx page. So when you open/launch the website you are presented with a login screen. If you investigate the login page there is a list of script files loaded even if you never get to the subsequent page that use one of these script files. The second problem is that RequireJS also (sometimes) times out and some scripts are not loaded properly.
The problem I have is the following:
I need to strip out the scripts that is not needed at login stage and only include these scripts when needed. This means: still using RequireJS load the common script files in the main aspx and then when navigating to content pages include/append the additional script files without losing the common ones.
How do I accomplish this? Is there a way to sub load scripts?
What I have tried:
- Use require("script1", "script2", "script3"); in main
- Then use require("script4a", "script4b"); to add additional scripts. But this approach removes the common scripts ("script1", "script2", "script3") and only loads ("script4a", "script4b"), and I have 2 references to require.js as well.

Good Day all
i am reluctantly maintaining a Classic Asp application that will be re-written in few months to come. i have an issue where i have a Code like this
if(document.frmEntry.optMethod != "undefined")
{
if (document.frmEntry.optMethod.selectedIndex == 0) {
strPrompt=strPrompt+'Please specify the Valuation Method\n';
if ( objFocus == null ) {
objFocus = document.frmEntry.optMethod;
}
}
}
my problem here is that even if document.frmEntry.optMethod is not equal to "undefined" the code still go into the condition as if it was true. i have attached a proof in my debuger.

Try using a Falsy check.
The following values are always falsy:
false
0 (zero)
"" (empty string)
null
undefined
NaN (a special Number value meaning Not-a-Number!)
Your code should look like as follows:
if(!document.frmEntry.optMethod)
{
if (document.frmEntry.optMethod.selectedIndex == 0) {
strPrompt=strPrompt+'Please specify the Valuation Method\n';
if ( objFocus == null ) {
objFocus = document.frmEntry.optMethod;
}
}
}
