I have a table and I want to know if its last td its id contains a certain string. For example, if my last td has id "1234abc", I want to know if this id contains "34a". And I need to do that in a 'if' statement.
if(myLastTdId Contains "blablabla"){ do something }
Thanks!!!
You could use the "attributeContains" selector:
if($("#yourTable td:last-child[id*='34a']").length > 0) {
//Exists, do something...
}
This is easily done with indexOf and last-child.
<table id='mytable'>
<tr>
<td id='abc'></td>
<td id='cde'></td>
</tr>
</table>
<script>
if($('#mytable td:last-child').attr('id').indexOf('d') != -1) {
alert('found!');
}
</script>
Here it would alert 'found' because d appears in the string cde
If your td is "bare" (i.e. not wrapped in a jQuery object), you can access its id attribute directly:
if (myTD.id.indexOf("34a") > -1) {
// do stuff
}
If it is in a jQuery object, you'll need to get it out first:
if (jMyTD[0].id.indexOf("34a") > -1 {
// do stuff
}
The indexOf function finds the offset of one string within another. It returns -1 if the first string doesn't contain the second at all.
Edit:
On second thought, you may need to clarify your question. It isn't clear which of these you're trying to match "34a" against:
<td id="1234abcd">blahblah</td><td id="blahblah">1234abcd</td><table id="1234abcd"><tr><td>blahblah</td></tr></table><table id="blahblah"><tr><td>1234abcd</td></tr></table>
Not completely clear if you mean last td in each tr, or the very last td:
if ($('#myTable td:last[id*=34a]').length) {
...
}
