Question

For my code, my drop down lists are initiated on the original page, via

<select name =country id=country 
onchange=showRecords(this.value,'country','province')>"

This function is taking the value, equating it to country, then querying MySQL, and setting the results where id=province, and creating cascading dropdown lists. This is obviously via Ajax.

So, when $_REQUEST[‘province’] is set, then the Province dropdown list gets populated with all provinces from the country to which it belongs, etc.; i.e.;

<?if(isset($province)){
echo "<script>showRecords('".$country."','country','province');</script>";}?>

However, for the life of me, I cannot figure out how I can set the default value equal to $_REQUEST[‘province’]. I cannot use the traditional way:

if (($selected) == ($value)) {
 $options.= " selected";
 }

Because it is querying the AJAX page with one piece of information at a time.

Any ideas would be greatly appreciated.

Answer 1

I have a lot of assumptions to your questions,

first is, if bydefault you have the select province like this

<select id="province">
 <option value=""></option>
 <option value="California">California</option>
 <option value="Washington">Washingthon</option>
</select>

then you can use this script to default select

document.getElementById("province").value="Washington"; 

---

but if bydefault you have the select province like this

<select id="province"></select>

then you can use this script to default select

document.getElementById("province").innerHTML='<option value="Wahsington">Washington</option>'; 

so it depend on your code and your need. maybe if you have another case the problem should be solved in another way.
