saving the dropdown value selected

[smellykat]

I have an html page - page1 - which has some input fields on it. One is a dropdown list. I need a way to pass/save whatever value was selected in the dropdown, so that when i come back to that page from calling page2, the value is selected.


This is how i am passing the other values of the page:


parent.hidframe.form1.vitem-hold.value="' vitemno '"; parent.hidframe.form1.vqty-hold.value="' vquantity '";


How can I use parent.hidframe for a dropdown? When I use the name of the dropdown like I did for the above 2 fields, I get this error: "parent.hidframe.form1.uomdropdown is not an object."


Thanks.

You have to use this:

parent.hidframe.form1.uomdropdown.options[parent.hidframe.form1.uomdropdown.selectedIndex].value;

Instead of that very long statement I'd use this:

dropdown = parent.hidframe.form1.uomdropdown;
and then:
dropdown.options[dropdown.selectedIndex].value

But remember that you cannot assing any new value to select list option this way! It is used only to read the value of the selected option.

Ok so I use that statement where? I have my dropdown defined like this:

<select name=&quot;uomlist` i `&quot; TABINDEX=&quot;` (i + 1)`&quot;>

dont I need an onchange or onclick in there to capture the value?

Using onchange is the most easy way:

<select ... onchange=&quot;getValue(this.options[this.selectedIndex].value)&quot;>

This way you'll pass the value of selected list item as a parameter of getValue() function.

I'm getting a syntax error with this line of code:

eval(&quot;parent.hidframe.form1.uomlist&quot; + i + &quot;.options[parent.hidframe.form1.uomlist&quot; + i + &quot;.selectedIndex].value=' &quot; + document.detailform.uomlist1.options[parent.hidframe.form1.uomlist.selectedIndex].value + &quot; ' &quot;

the error is :
parent.hidrame.form1.uomlist.selectedIndex is null or not an object

It's impossible to tell anything with this piece of code.

Lets back up a little. I'm unclear as to what to do in the getvalue() function. Can you clarify?

 

[starway]

Do there anything you want. You wanted to pass a value to the function? You did it. Then do with it whatever you need:

function getvalue(the_value) {
//example, in case it's numeric:
if (the_value > 20)
{
// do something
}

//example, in case it's literal:
if (the_value != &quot;some string&quot
{
// do something else
}
}

In the getvalue function, how can I assign the selected dropdown value to a hidden field so that I can pass it to another page?

 

[smellykat]

I keep getting the same error when I use this :

parent.hidframe.form1.uomdropdown.options[parent.hidframe.form1.uomdropdown.selectedIndex].value;


I get &quot;parent.hidframe.form1.uomdropdown.options is null or not an object&quot;.

document.formName.hiddenFieldName.value = the_value;
