No, as I said earlier, go and look at the documentation and the tutorials.
One of these days I'm going to think of a really clever signature.

Hey guys.
I'm looking to do some Javascript validation for drop down lists. I have the idea, I think, I just can't get it to work.
Heres the javascript
function Test() {
var ddlDevice = document.getElementById("<%=ddlDeviceType.ClientID%>");
if (ddlDevice.value == "---Please Select---") {
window.alert("Test");
ddlDevice.focus();
return false;
}
Heres the code behind
ddlDeviceType.Attributes.Add("onblur", "Test()");
I need it to be client side, and this kid of style, if that makes sense?
Thanks Guys

Add this to your dropdown control in aspx page .
onChange="javascript:ddlClick()"
<asp:DropDownList ID="DropDownList2" runat="server" onChange="javascript:ddlClick()"></asp:DropDownList>
<script type="text/javascript">
function ddlClick()
{
}
</script>

The <%client.id %> is for when your object is on a webform.
in code behind, you have to use a static id value.
So make sure the object exist first, it not, then it's your id, and javascript could not find it.
function Test() {
var ddlDevice = document.getElementById("_ddlDeviceType");
alert(ddlDevice);
if (ddlDevice.value == "---Please Select---") {
alert("Test");
ddlDevice.focus();
}
return false;
}
ddlDeviceType.Attributes.Add("id", "_ddlDeviceType");
ddlDeviceType.Attributes.Add("onblur", "Test(); return false;");

I wrapped up this code, did a final test, and it doesn't work on IE8 in XP and Server 2003. I tested it on firefox, Windows Vista IE, with developer mode for IE7, 8 and 9, works fine.
I can't get it to render in the DOM, and I'm completly baffled by it.
This is the simple part of the code. There's a more complex half not posted, and I really like the way createElement works, like creating html in code behind, it's easy to follow.
I remember reading something about createElement not working very good in IE8, but I can't find the web site again.
I tried document.body.appendChild(table_Progress) just as a test, but it still didn't render.
var table_Progress = document.createElement("table");
table_Progress.id = "_table_Progress";
table_Progress.setAttribute("cellpadding", "0");
table_Progress.setAttribute("cellspacing", "0");
table_Progress.setAttribute("border", "0");
table_Progress.style.width = "100%";
var tr_Progress_Image = document.createElement("tr");
table_Progress.appendChild(tr_Progress_Image);
var td_Progress_Image = document.createElement("td");
td_Progress_Image.style.width = "100%";
td_Progress_Image.style.height = "240px";
td_Progress_Image.style.verticalAlign = "bottom";
td_Progress_Image.style.textAlign = "center";
td_Progress_Image.style.margin = "0px auto";
tr_Progress_Image.appendChild(td_Progress_Image);
var image_Progress = document.createElement("img");
var imgProgress = $('[id*="_txt_JQuery_ImageBrowser_LibraryProgress"]').val();
image_Progress.src = imgProgress;
td_Progress_Image.appendChild(image_Progress);
var tr_Progress_Message = document.createElement("tr");
table_Progress.appendChild(tr_Progress_Message);
var td_Progress_Message = document.createElement("td");
td_Progress_Message.style.width = "100%";
td_Progress_Message.style.height = "240px";
td_Progress_Message.style.verticalAlign = "top";
td_Progress_Message.style.textAlign = "center";
td_Progress_Message.style.margin = "0px auto";
tr_Progress_Message.appendChild(td_Progress_Message);
var span_Progress_Message = document.createElement("span");
span_Progress_Message.style.color = "rgb(0,0,0)";
span_Progress_Message.style.fontSize = "2.0em";
span_Progress_Message.style.fontWeight = "bold";
span_Progress_Message.innerHTML = "Generating Product Library Browser";
td_Progress_Message.appendChild(span_Progress_Message);
$('[id*="_panel_Preview_Object"]').empty();
$('[id*="_panel_Preview_Object"]').append(table_Progress);

ie8 is really strict, so it was a matter of dotting the i's and crossing the t's.
If you make a small mistake, there is no warning, so like on the span tag, it's innerText and not innerHtml.
On tableRow's, it's insertRow(-1),
and on tablecell's it's insertCell(-1)
[EDIT]
Well after hours of reading last night, I found out that I'm running IE7, even though it's IE8 on XP and Server 2003. I also learned that IE7 and IE8 have there own version of creating html markup using createElement and appendChild.
So it's a matter of learning which properties work in both Gecko based browsers and IE, and which don't. It's sort of like VHS and Beta, they look the same, but are different.
I tried testing for createElement, to see if the DOM created it, by adding an ID to the element, and going back and checking the value, to maintain 1 version, but the element was created and an ID was assigned anyway on both.
So for now, I just did a browser check, and switch between the 2 versions.
I thought I was doing pretty good with Javascript and Jquery, but I have much more to learn about it, or I'm just using both more now and taking it to much higher levels now.

Good day
i am new to knockout ,
I am bringing back the data from a control and i am doing the autocomplete and i show the results in a listbox as depicted below
$(function () {
$("#txtSearchString").keyup(function () {
$("#lstSearchOptions").hide('fast');
if ($("#txtSearchString").val().length >= 3)
{
var data = {}
data.searchString = $("#txtSearchString").val();
$.getJSON("/SearchCars/SearchCars", data, function (result) {
var viewModel =
{
SearchOptions: ko.observableArray(result),
}
ko.applyBindings(viewModel,document.getElementById("stSearchOptions"));
ko.applyBindings(viewModel, document.getElementById("selectedcarid"));
if (result != null)
{
$("#lstSearchOptions").show('fast');
}
});
}
});
});
now when the user select something i need to get the selected ID and i also want the Year and this is my HTML
<select id="lstSearchOptions" data-bind="options: SearchOptions, optionsText: function(item) {
return item.Model + ' ' + item.Type + ' ' + item.Year}, optionsValue: 'CarId'"
multiple="multiple" size="-1" class="searchOptions">
</select>
and i have this to assign the value
$(function () {
$("#lstSearchOptions").change(function () {
$("#selectedcarid").val($("#lstSearchOptions option:selected").val());
});
$("#lstSearchOptions").blur(function () {
$("#lstSearchOptions").hide("fast");
});
});
so i can get the ID from here
$("#selectedcarid").val($("#lstSearchOptions option:selected").val());
but have a Problem to getting the year
Thanks

Hi all,
This is hopefully a very simple question however I do not know the answer to it.
I am trying to link a cell from a table created in Javascript to another function.
var cell_1 = document.createElement("td");
cell_1.style.textAlign = "center";
cell_1.appendChild(document.createTextNode("Hi"));
onclick = myFunction();
This code ALL works apart from the onclick function, all I wanted to do is when the cell is clicked for example an alert message pops up.
Hopefully that makes sense and if anybody can help that would be helpful 
|
|

|

Hi, you're basically there. Just 2 points:
- the onclick function belongs to cell_1
- You want to set the address of the function, not the result
cell_1.onclick = myFunction;
|
|
|
|
|
It might be better to create an a tag with a javascript: url:
var cell_1 = document.createElement("td");
cell_1.style.textAlign = "center";
var link = document.createElement("a");
link.appendChild(document.createTextNode("Hi"));
link.href = 'javascript:myFunction()';
That way, you get the usual link semantics (underlining, colour cues, cursor, tab order entry).
|
|
|
|
|
alternet way
cell_1.onclick = new Function ('myFunction()');

to attach events see this
// +++++ attach even
function AtEv(X00,X01,X02,X03)
// X00 pointer of object with event
// X01 kind of event, string e.g. 'mouseover'
// X02 pointer of event handler
// e.g. keyDownTextField (e)
// {
// var keyCode = e.keyCode;
// //...
// }
// X03 false bubbling event allowed
// true bubbling event not allowed: Capturing of event thru handler
// must be identical with avent deatch
// returns true if event attched
{
var X04=false;
// insert here checking of pointer and string ...
if(X00.attachEvent)
{
X04=X00.attachEvent('on'+X01,X02);
}
else
{
if(X00.addEventListener)
{
X00.addEventListener(X01,X02,X03);
X04=true;
}
}
return X04;
}
// +++++ detach event
function DatEv(X00,X01,X02,X03)
// params see AtEv
{
var X04=false;
// insert here checking of pointer and string ...
if(X00.detachEvent)
{
X04=X00.detachEvent('on'+X01,X02);
}
else
{
if(X00.removeEventListener)
{
X00.removeEventListener(X01,X02,X03);
X04=true;
}
}
return X04;
}
example
function EventHandler(e,X00)
// e.g. X00 param
// e placeholder for event
{
// do something with X00 and or e
}
// ----- create dynamic event handler
var pointerOfDynamicEventHandler=new Function('e','EventHandler(e,' + here the value of X00 + ')');
// check pointer ...
// ----- attach dynamic event handler
var booleanFlag=AtEv(pointerofObjectWithEvent,'click',pointerOfDynamicEventHandler,false);
// ------ don't forget to deatch event if you this not need

the problem is already solved 
var id = 1;
function novoCampo()
{
var inp = document.createElement("input");
inp.setAttribute("id", +id );
inp.setAttribute("name", "data_cadastro_"+id+"");
var lab = document.createElement("label");
lab.setAttribute("id", "l", +id);
lab.setAttribute("lab", +id);
var lab_content = document.createTextNode("");
var quebra = document.createElement("br");
var inpP = document.getElementById(id-1);
var parentInp = inpP.parentNode;
parentInp.insertBefore(lab, inpP.nextSibling);
parentInp.insertBefore(inp, lab.nextSibling);
parentInp.insertBefore(quebra, lab);
document.getElementById(+id).setAttribute('onclick',"javascript:popdate('document.form_funcionario.data_cadastro_"+id+"','pop3','150',document.form_funcionario.data_cadastro_"+id+".value)"); // for FF
//document.getElementById(+id).onclick = function() {javascript:popdate('document.form_funcionario.data_cadastro_'+id+'','pop3','150',document.form_funcionario.data_cadastro_+id+.value)}; // for IE

Hi,
i have the below code
var copy = "CATCOMETACISTCASEATCORACT";
var reg = /(CAT)+/;
var sd = copy.match(reg);
sd returns me only array with values [CAT,CAT] but i need diff combinations like
"CAT","CTA","TAC","ACT","ATC","TCA"
wat should the exact regular expression for the above result...
|
|
|
|
|
Just added modifiers - 'i' for ignore case and 'g' for global search
var copy = "CATCOMETACISTCASEATCORACT";
var reg = /([CAT]){3}/ig;
var sd = copy.match(reg);
Hope this may help you.
Regards,
Niral Soni

Doesn't work. Your regex will accept "CCC" "CCA" "TTT" "ATT" etc, which is not what OP wants.
