How can I make a for loop in jQuery?

Question

I need to have a for loop inside my jQuery.

Example:

  for(i=0;i<counter;i++)
   {
    $("div"+i+"").click(function(){//some code});
   }

How can I accomplish this?

EDIT:

This code was posted by the OP in a comment to one of the answers:

$("#displayPanel div").click(function (){ alert($(this).attr("id")); } 

<div id="displayPanel" class="displayPanel"> 
  <div id="heading"> Display Panel </div> <br/> 
  <div id="save" class="saveClass"></div> <br/> 
  <div id="field1" class="my"> 
    <label id="labelstr1">Untitled1</label> 
    <input id="inputstr1" type="text"/> 
  </div> 
  <div id="field2" class="my"> 
    <label id="labelstr2">Untitled1</label> 
    <input id="inputstr2" type="text"/> 
  </div> 
</div>

The alert is showing me the id for the first two divs and not for the field1 and field2.

Note:

The Field1 and Field2 divs are created on the fly.

Answer 1

You can, for example, loop through all div's like this:

$("div").each(function() {
    $(this).hide(); // this points to the current element
});

Answer 2

The loop seems unnecessary since the selector for div will apply to all divs.

$("div").click(function(){
  //this will apply to any div you click on the page
  //for example:
  $(this).css('color','red'); //change the color of the div clicked to red
});

EDIT: Since you mention in the edit that #field1 and #field2 are created on the fly, then you need to use .live() to bind the click event as shown below:

$("#displayPanel div").live('click', function(){
  alert($(this).attr('id'));
});

Answer 3

Do these divs have a common parent, attribute, or anything else? Matching by IDs of a certain form (i.e. divXYZ in your case) probably isn't the easiest/most obvious thing to do. The API documentation for Selectors has a complete list of the different ways you can select elements. Choose whichever is most appropiate for, and the JQuery becomes much simplified.

Here's an example for selecting divs with a common parent:

$("#parent > div").click(function() {
    // some code
});

And for selecting divs with a common attribute (if they don't have a common parent one solution could be giving them each a cusotm attribute):

$("div[fooAttribute]").click(function() {
    // some code
});

Yes you can have a for loop in jQuery, but by the look of your question, you might not need it. When you use

$('div').click(function(). { ... });

You can bind the function as an event handler for all divs with one command. You can also use context, a class name or other attributes to filter the divs to which the event handler is applied.

If you wanted to perform a different action for each div, you would be best to have a unique ID on each div and then bind an event handler using

$('#divId').click(function() { ... });

Answer 5

You can put the divs with a common class

<div id="d1" class="your_css_class your_control_class">
<div id="d2" class="your_css_class your_control_class">
<div id="d3" class="your_css_class your_control_class">
<div id="d4" class="your_css_class your_control_class">
<div id="d5" class="your_css_class your_control_class">

$(".your_control_class").click(function(){
   var div_id=$(this).attr("id"); // gives you the ID of the clicked div
   if(div_id==="d1") functionForDiv1();
   else if(div_id==="d2") functionForDiv2();
   ...
});

EDIT:

If you have everything inside that big div then you can do:

$("#displayPanel > div").click(function(){
...
