I am trying to dynamically create elements and hence dynamically giving them the value. So if I want to access an element using a value which is stored in a variable, how do I do that ?
I've tried using $("#'"+g+"'")
but it didn't work
var text1 = '<div id="' + g + '"></div>';
var text2 = '<input data-checkbox="' + g + '" type="checkbox" style="display:none;"/><h3 data-header="' + g + '" style="display:inline-block;">Timer' + g + ' </h3><input data-input="' + g + '" type="text" style="display:none;"/>';
var text3 = '<span data-minutes="' + g + '">00</span>:<span data-seconds="' + g + '">00 </span><button data-start="' + g + '" >start</button><button data-stop="' + g + '" style="display:none;">stop</button><button data-clear="' + g + '" style="display:none;">clear</button>';
$('#header').append(text1);
$("#'"+g+"'").append(text2, text3);
This should be all you need:
$("#" + g)
The fact it's a string is already implied.
You're quite close to getting this right; the comments are trying to tell you that you aren't forming the selector correctly.
The selector for an id must be a string in the form:
'#id'
In your example you have too many '
symbols, so the id from your variable g
will be in the string, but surrounded by variables. If g
was test-id
, you'd have the string:
"#'test-id'"
...and jQuery can't match that.
All you need to do is take out those quotes, here's how that might look:
var g = 'any-id'; var text1 = '<div id="' + g + '"></div>'; var text2 = '<span>Some other text</span>'; $('#header').append(text1); $('#' + g).append(text2);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="header">Header is here</div>
You just have a small mistake.
You need to try like this $("#"+g).append(text2, text3);
var g = "data"; var text1 = '<div id="' + g + '"></div>'; var text2 = '<input data-checkbox="' + g + '" type="checkbox" style="display:none;"/><h3 data-header="' + g + '" style="display:inline-block;">Timer' + g + ' </h3><input data-input="' + g + '" type="text" style="display:none;"/>'; var text3 = '<span data-minutes="' + g + '">00</span>:<span data-seconds="' + g + '">00 </span><button data-start="' + g + '" >start</button><button data-stop="' + g + '" style="display:none;">stop</button><button data-clear="' + g + '" style="display:none;">clear</button>'; $('#header').append(text1); $("#"+g).append(text2, text3);
