GetElementsByName With Options

Jan 11, 2007

I've tried to access the value of a selected option through the
following getSelectValue function, passing the name of the select

function getSelectValue (name) {
var sel = document.getElementsByName(name)[0];
var i = sel.options.selectedIndex;
return i == -1? "": sel.options[i].value;
}

getSelectValue ('belongsto')
...
<select name="belongsto" ...

yet I always get the error "sel has no properties". Any idea what's
wrong? Is there a simpler way?

GetElementsByName()

Mar 13, 2006

I want to use document.getElementsByName('name').value to retrieve a
value of the field 'name', but it returns undefined.
But function document.xxxform.name.value returns the correct value.

I thought this 2 functions are identical? If getElementsByName is not
the same as the later function, is there any other function I can use
which is same as document.xxxform.name.value, but allow me pass in a
variable name of the 'name'?
I want to do something like:

var name = 'label'+i
text = document.getElementsByName(name).value

GetElementsByName() - Opera X Firefox

Apr 20, 2006

I'm trying to get all the "divs" that have a given NAME using
getElementsByName(). For example, the following code:

<html>
<head>
<script type="text/javascript">

function on_load()
{
var pages = document.getElementsByName("name");
alert(pages.length);
}

</script>
<body onload="on_load()">
<p name="name" id="id">Teste</p>
</body>
<html>

when I open this page in Firefox, it gives me a popup saying "1", that
is correct. But if I do it in Opera, it gives me "0"....

Document.getElementsByName(id) Gives Error 'undefined'?

May 29, 2011

I am trying to add a green tick or red cross to my form so that the user will know if they have filled out the form correctly before submitting it and getting told that they need to fill out this or correct that.I have added NAME to each form field and have been using this to read the content but for some reason I am unable to read what is in the field I get the error, 'undefined'.this is what code I have started on...

function checkValidFormInput(id, noCheck) {
if (noCheck == '') {
var idValue = document.getElementsByName(id);[code].....

my code is still in the early stages and is missing the other parts to place a red cross, as the moment i am working on placing the green tick.what I have wrong in my code that is causing it not to read the form field.my form field is coded as so..

<li class="value">
<input type="text" autocomplete="off" name="customerName" value="<?=$fullname;?>" style="width: 200px;" onChange="checkValidFormInput(this.name, '');">
<div style="float: left;" id="customerNameImg"></div><br style="clear:both">
</li>

Problem Using GetElementsByName On 2 Dimensional Array In IE

Aug 17, 2007

How can I fetch a part of the array in IE?

The code works as expected in Opera and Firefox, but IE returns an error saying that matchPaid does not contain a value.

As it seems IE does not pull any of the input fields belonging in the array.

I believe the issue lies in this line:

var matchPaid = document.getElementsByName("plan_bonus_amount["+key+"][]");

The rest of the function:

JavaScript Code:

function updateMatchPowerline(total, newPlan) {
    var totalPlan = parseInt(document.getElementById("total_plans").value);
    var totalMatch = document.getElementById("total_match");
   
    if (newPlan === true) totalPlans = totalPlan + 1;
    else totalPlans = totalPlan;
   
    var matchValue = 0;
   
    for (var key=0;key < totalPlans;key++) {
        var div = document.getElementById("match_table_"+key);
        var newTbody = document.createElement("tbody"); 
       
        var match = new Array();
       
        if (key < totalPlan && parseInt(totalMatch.value) > 0) {
            /*Fetch the current values, then clear the table*/
            var matchPaid = document.getElementsByName("plan_bonus_amount["+key+"][]");
           
            for (var nr=0;nr < parseInt(totalMatch.value);nr++) {
                match[nr] = parseFloat(matchPaid[nr].value);
            }
           
            remove(div);
        }
       
        for (var nr=0;nr < total;nr++) {           
            if (typeof(match[nr]) != 'undefined') matchValue = match[nr];
            else matchValue = 0;
       
            newTbody = createMatchPowerline(newTbody, key, nr, matchValue);
        }
       
        div.appendChild(newTbody);
    }
   
    totalMatch.value = total;
}

Does anyone have an idea on how I can fetch those values in IE?

GetElementsByName With Multi-Criteria Values?

Sep 24, 2011

I am trying to adapt an existing script which returns a list of URLS from my website based on an entry in a search box. I would like to adapt it so that I can enter a value other than the string value "xxx" but so that I can search for "xxx" or "yyy". I can see that the script uses the function GetElementsByName with a Name value. Is there any way that I can change the value of the Name to be '"xxx" or "yyy"' instead of just "xxx" or should I be using a different function?

Getting Options Title

Apr 21, 2006

I have an some options like this:

<option value="12345" title="Frank">Frank - 12345</option>

What I want to do, is get the title. I've tried this:

document.MyForm.MySelect.options[document.MyForm.MySelect.selectedIndex].title

That dosn't work. I'm just using the title attribute as a place to hold the information I need. Maybe there is another attribute that would work better for this? How can I get the contents of the attribute?

Selecting All Options In A Dropdown

Jul 23, 2005

I have a drop down with alot of options say about 6000 cities and
districts. I need to select all options if user selects "All checkbox".
I use "on change" and a for loop to do this, but it takes a lot of time
to select all these options. Is there any faster way to select all
these options?

function selectAll()
{
var element = document.getElementById("location");
var length = document.getElementById("location").length;

for(var i=0; i<length; i++)
{
element.options[i].selected=true;
}
}

Changing Drop Down Options

Jul 23, 2005

I have two drop down box's in a form, how would I go about changing the
options of the seccond one depending on what option is selected in the
first one?

For example, if there's a drop down box with "a", "b" and "c" as the
options, and another drop down box with "1", "2" and "3" as the
options; then when you select "a" on the first drop down box the values
of the seccond one changes to "a1", "a2" and "a3". This should work for
all the options of the first drop down box.

optionObject = document.getElementById(what.name+optionValue);
if (optionId!=selectedId) {
optionObject.className="hidden";
}

Script Source Options

Oct 14, 2006

I notice when I view the source of a lot of Google pages (for example,
my GMail Inbox page source) that the src option in <scripttags will
refer to addresses like "?foo=bar&bla=bla". How does this work
exactly? Does the server side script return a string containing
javascript code? How does it know which server side script to call?
Does it look for an index file of some type?

Something else I just noticed in the address of this page (I know this
is off topic, sorry)... this page sends GET data to a "place" named
'post', but 'post' has no file extension. How does this work?
