Setting a var value

[SDyke]

I am using javascript in a lotus notes web client. The following code creates an error:

function displayWarning(){
stop_order_flag = new String(window.document.forms[0].dm_stop_order.value);
}

window.document.forms[0].dm_stop_order.value is null or not an object

Please help

What the error is telling you is that window.document.forms[0].dm_stop_order does not exist on your page. This could mean a few things. Either there's no forms on your page, or there's no element with a name of dm_stop_order on the page, or specifically there's no element with the name dm_stop_order in the first form on the page. Without seeing the markup for the page it's impossible to tell you which of those problems I've listed that it is.

Try removing the window part from your object -think it'll solve your problem.

Change this :

window.document.forms[0].dm_stop_order.value

To this :

document.forms[0].dm_stop_order.value

 

[cLFlaVA]

consequently, your code should be

stop_order_flag = document.forms['your_form_name'].elements['dm_stop_order'].value;

or, preferably:

stop_order_flag = document.getElementById('yourFieldId').value;

I think you are right about the form not existing.

On an intranet web page a link opens a notes form with a prompt box. User types a number in and a document opens with data pertaining to number. My desire is to have an alert pop up if a certain field contains a specific text string. However I can't seem to get my syntax right in the JS Header to poll for the value of a field.

When I try:

stop_order_flag = document.getElementById('yourFieldId').value;

I get message that 'Object is required'

You need to use the ACTUAL field name you're looking for, not just copy and paste examples given here. Do you actually have a field named yourFieldId? Or is it named dm_stop_order?

As well, I'd break it into 2 steps to see if the element exists before trying to access its value.

var element = document.getElementById('yourFieldId');

if (element)
  {
  var stop_order_flag = element.value;
  }

This code returns 'undefined' Even though I do have a field named 'DM_STOP_ORDER' and it have a string value also.

function displayWarning(){

var element = document.getElementById('DM_STOP_ORDER');

if (element)
{
var stop_order_flag = element.value;
}

alert(stop_order_flag);

}

 

[trollacious]

Is the element named DM_STOP_ORDER, or does it have the id DM_STOP_ORDER? The function clearly is called getElementBy[/red]Id[/red].

document.getElementBy[red]Id[/red] looks for an element with an ID of what you specify. Not NAME.

Make that getElementBy[red]Id[/red].

There's also a method document.getElementsByName() that returns an array of elements with the specified name, and you have to access it as an array.

That's what I get for not previewing what I wrote. #

I am getting closer but this code returs "Hit" even when redlineflag and element3 do not match.

function displayWarning(){

var element = document.getElementById('DM_STOP_ORDER');
var element2 = document.getElementById('DM_FILES2');
var element3 = new String("SEE REDLINE DRAWING");

if (element)
{
var stop_order_flag = element.value;

}

if (element2)
{
var redlineflag = element2.value;

}

if(stop_order_flag)
{
alert("There is a Stop Issued for this Drawing");
}

if(redlineflag=element3)
{
alert("Hit");
}
else{
alert("None")
}
}

Never mind. I just realized I need == to compare variables.
