Q898 How can I update three text boxes with different information when an option from a pull down menu is selected?
The most compact way is to store three different items of data in each
of the options value property separated with &:
<script language="JavaScript"><!--
function updateForm(what,count) {
selected = what.mySelect.selectedIndex;
value = what.mySelect.options[selected].value;
for (var i = 0, oldpos = -1; i<count-1; i++) {
pos = value.indexOf('&',oldpos+1);
data = value.substring(oldpos+1,pos);
what.elements['text' + i].value = value.substring(oldpos+1,pos);
oldpos = pos;
}
what.elements['text' + i].value = value.substring(oldpos+1,value.length)
}
//--></script>
<form>
<select name="mySelect" onChange="updateForm(this.form,3)">
<option value="red&hot&inside">0
<option value="black&warm&outside">1
<option value="blue&cold&above">2
</select>
<input type="text" name="text0">
<input type="text" name="text1">
<input type="text" name="text2">
</form>
<p>
And another form with four text boxes:
</p>
<form>
<select name="mySelect" onChange="updateForm(this.form,4)">
<option value="red&hot&inside&today">0
<option value="black&warm&outside&tomorrow">1
<option value="blue&cold&above&yesterday">2
</select>
<input type="text" name="text0">
<input type="text" name="text1">
<input type="text" name="text2">
<input type="text" name="text3">
</form>
|
Which can be extended to hold as many items of data as required.
