Strange Jquery 1.3 behavior
Today I worked with two elements with same ids but in different forms, and found strange jquery selector engine behavior. Actually I can undrestand that, because by w3c you cant place two elements with same ids on same page.
Description: Two froms with element with same id in both of them, trying to use jquery selector to choose one of them like this $(“#formid #elemid”). Result will be null.
Example:
HTML:
<form id="form1" method="post" action="/">
<input type="text" class="inputtext" id="text1" name="text1" value=""/>
<input type="text" class="inputtext" id="text2" name="text2" value=""/>
<input type="text" class="button" id="btn1" value="press me"/>
</form><form id=”form2″ method=”post” action=”/”>
<input type=”text” class=”inputtext” id=”text1″ name=”text1″ value=””/>
<input type=”text” class=”inputtext” id=”text2″ name=”text3″ value=””/>
<input type=”text” class=”button” id=”btn2″ value=”press me2″/>
</form>
