How to attach click event at runtime when i have all ids in an array that gets populated when document is ready?
I have the following code,
<script type="text/javascript">
$(document).ready(function () {
var dataAnalysisDataFileTableIDs = $("#dataAnalysisDataFileTable tr[id]").map(function () { return this.id; }).get();
//for(var key in dataAnalysisDataFileTableIDs) {
// var id = "#" + dataAnalysisDataFileTableIDs[key];
// $(id).click(function () {
// alert("[" + index + "][" + value + "]");
// });
//}
//$.each(dataAnalysisDataFileTableIDs, function (index, value) {
// var id = "#" + dataAnalysisDataFileTableIDs[key];
// $(id).click(function () {
// alert("[" + index + "][" + value + "]");

//});
$("#dataAnalysisDataFileTable tr[id]").each(function (i, elem) {
$(elem).click(function () { alert("[" + i + "][" + this.id + "]"); });
});
$("#aaa").click(function () {
alert("meow");
});
});
</script>
and it doesn't work i also tried the one in the comments section which does the same as "for in" it doen't work but when i attach click to the id #aaa it works fine how do i approach this problem when i have all the ids in the array and i want to be able to attach events to them?
How about just using each ? Like so:
<html>
<head><script type="text/javascript" src="http://code.jquery.com/jquery-1.6.4.min.js"></script></head>
<body>
<table id="dataAnalysisDataFileTable">
<tr id="foo"><td>foo</td></tr>
<tr id="bar"><td>bar</td></tr>
</table>
<script type="text/javascript">
$(document).ready(function () {
$("#dataAnalysisDataFileTable tr[id]").each(function(i, elem) {
$(elem).click(function() { alert("[" + i + "][" + this.id + "]") } );
});
});
</script>
</body>
</html>
I've patched the possible errors. I cannot resolve the value variable though.
for(var index=0, length=dataAnalysisFileTableIDs.length; index++) {
var key = dataAnalysisFileTableIDs[index];
var id = "#" + dataAnalysisFileTableIDs[key];
$(id).click(function () {
/* Value ? It's not defined*/
alert("[" + index + "][" + /*value +*/ "]");
});
}
dataAnalysisFileTableIDs is an array. To loop through an array, you have to use the for ( init_index ; condition ; increment ) loop. The key can be obtained through name_of_array[index].
