You didn't mention what language you are using on your server side, but it is your server side code that should handle those requirements. JavaScript or jquery has nothing to do with it.

The following are my requirement before asking this to you people am really too tired of finding solution for that issue..
hope you guys help me..!!
well,
1. I'Ve a dropDwonList with 50 items.
if user select or change multiple values based on their requirement, the dropdownlist should be added one by one.
now, i need to save the user selected values from dropdown in database. here am using AngularJS and MonogoDB, Javascript (am totally new AngularJs).
for Example
------------
DropDownList1 , if user select the item from this, it should be saved in DB as first item,
if he/she wants to add more items from list, it will also should be added.
Clearly, number of times to click = total number of items should be saved in db..
hope you understand.
please help me to complete this.

No idea what you are talking about

Sir, am asking about, how to store selected multiple values from dropdownList in database
|
|
|
|
|
What is your question exactly?
There are only 10 types of people in the world, those who understand binary and those who don't.

Well, Sir am asking about how to store selected multiple values from DropDownList to database
|
|
|
|
|
Capture the values from the list and insert them into the database with an SQL statement. Exactly which part of the process are you having difficulty with?
|
|
|
|
|
well am using MonoDB,
the problem is if the user want to add more items means, they can click add button which creates DrpDwnlist dynamically as per number of times they want.
after all i want to save those in db. how?
if user have 5 dropDwnlist with different values means it should be saved in db or atleast in array
|
|
|
|
|
You are just repeating what you want to do, but you have not explained what the coding problem is. Adding items to your database is quite straightforward, and you should be able to find samples and tutorials via Google.

am getting confusion sir, i really don't get any ideas to write this particular code..!!!  can't figure it out..!!!

Add a new record that stores what the drop down is and what value they picked. All you have to do is think of what data do you need to store and then create a table that stores that data.

i have used Jvector Map.its display country from default. i have created simple database and connected jquery ajax my database value using only alert only. but i want display database value when i click country.
Here attach my code:
jQuery.noConflict();
jQuery(function(){
var $ = jQuery;
$('#focus-single').click(function(){
$('#map1').vectorMap('set', 'focus', {region: 'AU', animate: true});
});
$('#focus-multiple').click(function(){
$('#map1').vectorMap('set', 'focus', {regions: ['AU', 'JP'], animate: true});
});
$('#focus-coords').click(function(){
$('#map1').vectorMap('set', 'focus', {scale: 7, lat: 35, lng: 33, animate: true});
});
$('#focus-init').click(function(){
$('#map1').vectorMap('set', 'focus', {scale: 1, x: 0.5, y: 0.5, animate: true});
});
$('#map1').vectorMap({
map: 'world_mill_en',
panOnDrag: true,
focusOn: {
x: 0.5,
y: 0.5,
scale: 1,
animate: true
},
series: {
regions: [{
scale: ['#688FA0'],
normalizeFunction: 'polynomial',
values: {
"AG": 1.1,
"AR": 351.02,
"AU": 1219.72,
"AT": 366.26,
}
}]
},
onRegionClick: function (event, code) {
var map = $('#map1').vectorMap('get', 'mapObject');
var name = map.getRegionName(code);
$(document ).ready(function() {
$.ajax({
type: "GET",
url: 'database.php',
data: {country: name},
dataType: "text",
success: function(data){
alert(data);
}
});
});
},
});
})
</script>
database code:
<pre><pre><pre lang="PHP"> connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT countryId,country,pdogcoregion,ccl,category FROM countrydetails WHERE country='".$_country."'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "country: " . $row["country"];
}
}
else {
echo "No database";
}
$conn->close();
?>
Its showing country from default not from database .database value only show alert..how to change to click?

Do you have any preferences for below code code snippet? What approach do you follow when your site have too many fields.
Option 1:
PriorityOfAccessModel:
{
Id: $('#divPriorityAccess #Id').val(),
FamilyId: $('#divkPriorityAccess #FamilyId').val(),
ChildId: $('#divkPriorityAccess #ChildId').val(),
Comment: $('#divkPriorityAccess #Comment').val(),
CreatedBy: $('#divkPriorityAccess #CreatedBy').val(),
CreatedOn: $('#divkPriorityAccess #CreatedOn').val(),
Categories: accessPriority.getCategory(),
Allocating: { Id: allocating }
}
Option 2 :
var $x = $('#divPriorityAccess');
var accessModel =
{
Id: $x.find('#Id').val(),
FamilyId: $x.find('#FamilyId').val(),
ChildId: $x.find('#ChildId').val(),
Comment: $x.find('#Comment').val(),
CreatedBy: $x.find('#CreatedBy').val(),
CreatedOn: $x.find('#CreatedOn').val(),
Categories: accessPriority.getCategory(),
Allocating: { Id: allocating }
};
Option 3:
var $y = $('#divkPriorityAccess');
var accessModel =
{
Id: $('#Id', $y).val(),
FamilyId: $('#FamilyId', $y).val(),
ChildId: $('#ChildId', $y).val(),
Comment: $('#Comment', $y).val(),
CreatedBy: $('#CreatedBy', $y).val(),
CreatedOn: $('#CreatedOn', $y).val(),
Categories: accessPriority.getCategory(),
Allocating: { Id: allocating }
};
Context: Quote: $('.child', parentContext);
Ops/Sec: 105,442 ±7.03% fastest
Find: Quote: $(parentContext).find('.child');
Ops/Sec: 113,119 ±10.53% fastest
My above finding is based on
Quote: jQuery Selector Benchmark
Hope It will help.

It's always better to specify the context. Especially when we have a heavy DOM.
|

All three examples you have given are using ID selectors[^]. Since each ID within the document should be unique, there's no point specifying the ID of the parent element, using the .find method, or passing the parent element with the selector.
With an ID selector, jQuery uses the document.getElementById function, which is extremely efficient. All of your examples will require additional checks, which will slow your code down.
Also, by specifying the parent element's ID, your script is now tied to the layout of your document.
Therefore, I would prefer option 4:
PriorityOfAccessModel:
{
Id: $('#Id').val(),
FamilyId: $('#FamilyId').val(),
ChildId: $('#ChildId').val(),
Comment: $('#Comment').val(),
CreatedBy: $('#CreatedBy').val(),
CreatedOn: $('#CreatedOn').val(),
Categories: accessPriority.getCategory(),
Allocating: { Id: allocating }
}

I am trying to validate file upload along with a few other form fields.
All the form fields listed in the script below are being validate except the single file upload.
Any ideas what I am doing wrong?
<script type='text/javascript' src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/additional-methods.js"></script>
script type='text/javascript'>//<![CDATA[
$(document).ready(function () {
// We'll use this flag so we don't have to validate fields before
// the form has been submitted.
var validatingForm = false;
// This line before validate() is called allows
// chosen menus to be validated
$.validator.setDefaults({ ignore: ":hidden:not(select)" });
$('#form1').validate({ // initialize the plugin
invalidHandler: function() {
// Now we can validate the fields onChange
validateForm = true;
},
rules: {
errorElement: 'div',
txtBidDate: "required",
txtDueDate: "required",
BidTitle: "required",
BidID: "required",
CategoryID: "required",
BidIDFile: "required",
AliasID: "required",
BidContact: "required",
ContactEmail: {
required: true,
email: true
},
BidType: {
required: true,
},
BidStatus: "required"
},
messages: {
txtBidDate: "Please enter Issue Date",
txtDueDate: "Please enter Due Date",
BidTitle: "Please enter Project Title",
BidID: "Please enter ID",
CategoryID: "Please select a Category",
BidIDFile: "Please select a Bid File",

BidTitle: "Please enter Project Title",
BidType: {
required: "Please select Bid Type"
},
ContactEmail: "Please enter a valid email address",
BidStatus: "Please select Bid Status"
},
});
// Now set an onChange event for the chosen menu
$("CategoryID").change(function(){
// Check that we've tried to submit the form
if(validateForm) {
// We tried to submit the form, re-validate on change...just to get rid of the message
$("CategoryID").valid();
}
});
$("AliasID").change(function(){
// Check that we've tried to submit the form
if(validateForm) {
// We tried to submit the form, re-validate on change...just to get rid of the message
$("AliasID").valid();
}
});
$("BidType").change(function(){
// Check that we've tried to submit the form
if(validateForm) {
// We tried to submit the form, re-validate on change...just to get rid of the message
$("BidType").valid();
}
});
$("BidStatus").change(function(){
// Check that we've tried to submit the form
if(validateForm) {
// We tried to submit the form, re-validate on change...just to get rid of the message
$("BidStatus").valid();
}
});
});//]]>
</script>
<input type="file" id="BidIDFile" name="BidIDFile[]" value="" size="50">
Thanks in advance for your prompt assistance.

I don't follow all your code but the likely reason is because the file upload control renders as separate html controls. You'll need to validate the actual textbox that get rendered client side.
There are only 10 types of people in the world, those who understand binary and those who don't.

What a "fantastic" feedback!
Well, I fixed it myself and the problem was this BidIDFile[]
I played around and got it to work by using it like this:
"BidIDFile[]": "required" and it worked.

Good catch. This is mentioned in the documentation, but could probably be more prominent:
rules: ... Key is the name of an element (or a group of checkboxes/radio buttons), ...
So you have to use the name of the element, rather than its id.

How to write the javascript function for pass image from set of image to another image box?
|
|
|
|
|
Do you mean how to load a image in Javascript, or how to accept one as a parameter in Javascript?
Because if you just want to load a image in Javacript you can do the following:
create a variable to hold the image like so: var Img = new Image();
then assign the src of the image like so: Img.src = "/PathToMyImage.jpg";
