Javascript & PHP Problem parsing input data:

Sep 11.2004

This is what I use to go to .php when they change the info in the drop down field. I’ve noticed instead of parsing the data like a “submit formation, it just refreshes the page. Can I do this exact thing but state onchange, submit to file.php? Is this possible instead of just refreshing the data?

[code=php]
<tr>
<td width=”175″ height=”25″><font size=”2″># of Carts:</font></td>
<td width=”427″ height=”25″>
<select name=”Number_Of_Carts” onchange=”if(this.options[this.selectedIndex].id){top.location.href=this.options[this.selectedIndex].id;}return true;”>
<option selected></option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=1″ value=”1″>1</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=2″ value=”2″>2</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=3″ value=”3″>3</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=4″ value=”4″>4</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=5″ value=”5″>5</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=6″ value=”6″>6</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=7″ value=”7″>7</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=8″ value=”8″>8</option>
<option id=”mobile_vendors_pre_submit.php?state=<? $state = $_GET[‘state’]; echo $state; ?>&carts=9″ value=”9″>9</option>
</select>
</td>
</tr>

@Paul_JrSep 11.2004 — Assuming the Select element is within a form, and said form's action attribute points to the correct page;
<i>
</i>onchange="this.form.submit();"

However, you should also make sure the form works for users without JavaScript, so you could add something along the lines of:
<i>
</i>&lt;noscript&gt;
&lt;button type="submit"&gt;Submit Form&lt;/button&gt;
&lt;/noscript&gt;

Where you would want the submit button to appear.

@d_brandusaauthorSep 11.2004 — Okay, that works better, but it doesn't use the specified id"" url that I provided. How can I say onchange submit form with url provided in id based on what number they choose? If I can get that to work were set!

Success!
