jquery: click for every id-element starting with

I tried to find all ids starting with the string "matchItem_" and define a click-event for each. onclick i want wo execute a script with a URL parameter and change the image in this id-element. Unfortunately my syntax isn't right, I also tried with .each.function but I did开发者_C百科n't get it.

$('[id^="matchItem_"]').each {
    
    $(this).click(){
     //...execute my script.php?urlparam=xx....;
     $(this).find('img').attr('src','/admin/images/ok.png');
    }

}

You don't need the each:

$('[id^="matchItem_"]').click(function() {
   // do something
   $(this).find('img').attr('src','/admin/images/ok.png');
});

Your syntax is invalid because you forgot the functions.

$('[id^="matchItem_"]').each(function() {
    $(this).click(function(){
           //...execute my script.php?urlparam=xx....;
         $(this).find('img').attr('src','/admin/images/ok.png');
    });
});

Or if all you're doing is assigning the .click() handler, you can do it without the .each().

$('[id^="matchItem_"]').click(function(){
       //...execute my script.php?urlparam=xx....;
     $(this).find('img').attr('src','/admin/images/ok.png');    
});

This is because most jQuery methods will automatically act on every element in the jQuery object.
