JS:
<script type="text/css">
$(function() {
$('#upper').keyup(function() {
this.value = this.value.toUpperCase();
});
});
</script>
HTML
<div id="search">
<input type="radio" name="table" class="table" value="professor" tabindex="1" /> Professor
<input type="radio" name="table" class="table" value="department" tabindex="2" /> Department
<input type="radio" name="table" id="upper" class="table" value="course" tabindex="3" /> Course
<input type="text" name="search" class="keywords" value="Select an option..." onclick="this.value='';" onfocus="this.select()" onblur="this.value=!this.value?':this.value;" tabindex="4" />
<div id="content"> </div>
</div>
为什么这仍然不起作用？？只是想从JS中调用div".keywords".
