Question

I have a form in which a table of dynamic data is built with PHP. Within each row is an image that when clicked calls a jQuery function with a click event.

For example, if the image has an id of eventnfo_0, i have a function like this:

$("#eventnfo_0").click(function()

It all works fine as long as I have a defined click event for each row. The problem is, I need to make it dynamic because the number of rows can vary so it’s not feasible to build a separate function as depicted above for each row.

My thought is there must be a way to call a jQuery function from an onclick event and pass a row number, but thus far, no dice.

I’m sure it’s not an uncommon task, but I’ve not had any luck with my searches.

Any thoughts are appreciated.

Answer 1

there are many ways tyo do this… call a same class in each img and use it as a selector…

$('.yourClassName').click(function(){alert($(this).attr('id'));});

OR

 $("[id^='eventnfo_']").click(function(){
     alert($(this).attr('id'));
 });

since it is dynamically added this might help..

$(document).on('click',"[id^='eventnfo_']".click(function(){
     alert($(this).attr('id'));
 });

you can use a data attributes for a rownumber and get it from jquery..

say this is your html.

 <img id="eventnfo_0" data-rownumber="1"/>

and jquery

$("[id^='eventnfo_']").click(function(){
     alert($(this).data('rownumber')); //this will alert 1
 });
