jQuery '.each' and attaching '.click' event
JqueryEachJquery Problem Overview
I am not a programer but I enjoy building prototypes. All of my experience comes from actionScript2.
Here is my question. To simplify my code I would like to figure out how to attach '.click' events to div's that are already existing in the HTML body.
<body>
<div id="dog-selected">dog</div>
<div id="cat-selected">cat</div>
<div id="mouse-selected">mouse</div>
<div class="dog"><img></div>
<div class="cat"><img></div>
<div class="mouse"><img></div>
</body>
My (failed) strategy was:
-
make an array of objects:
var props = { "dog": "false", "cat": "true", "mouse": "false" };
-
iterate through the array with '.each' and augment each existing div with a '.click' event. Lastly, construct a local variable.
here is a prototype:
$.each(props, function(key, value) {
$('#'+key+'-selected').click(function(){
var key = value;
});
});
Jquery Solutions
Solution 1 - Jquery
One solution you could use is to assign a more generalized class to any div you want the click event handler bound to.
For example:
HTML:
<body>
<div id="dog" class="selected" data-selected="false">dog</div>
<div id="cat" class="selected" data-selected="true">cat</div>
<div id="mouse" class="selected" data-selected="false">mouse</div>
<div class="dog"><img/></div>
<div class="cat"><img/></div>
<div class="mouse"><img/></div>
</body>
JS:
$( ".selected" ).each(function(index) {
$(this).on("click", function(){
// For the boolean value
var boolKey = $(this).data('selected');
// For the mammal value
var mammalKey = $(this).attr('id');
});
});
Solution 2 - Jquery
No need to use .each. click already binds to all div occurrences.
$('div').click(function(e) {
..
});
Note: use hard binding such as .click to make sure dynamically loaded elements don't get bound.
