I have a JavaScript that changes the output on the same page by using:
<"a href="#" onclick="change('Bob','0','0','2','2','1','0','0')">Bob</a>
<"a href="#" onclick="change('Sam','0','0','2','2','1','0','0')">Sam</a>
<"a href="#" onclick="change('Ted','0','0','2','2','1','0','0')">Ted</a>
I would like to change the links to a dropdown (select - option) form field.
Any help putting me in the right direction will be appreciated.
<select size="1" onchange="change(this.value, '0','0','2','2','1','0','0')">
<option>Bob</option>
<option>Sam</option>
<option>Ted</option>
<select>
Using this.value
gives you the currently selected option of the select box (Bob, Sam or Ted).
EDIT
If you want to pass different parameters to your function, you can do it like this:
Javascript:
function selectValueChanged(value){
switch(value){
case "Bob":
change('Bob','-1','0','2','4','6','0','0');
break;
case "Sam":
change('Sam','0','-2','3','5','1','0','2');
break;
case "Ted":
change('Ted','2','1','4','2','3','2','0');
break;
}
}
HTML:
<select size="1" onchange="selectValueChanged(this.value)">
<option>Bob</option>
<option>Sam</option>
<option>Ted</option>
<select>
So you pass your selected value to selectValueChanged
, and this function calls the change
function with the appropriate paremeters.
