Javascript to get Item values

Question

Hi
I am very new to javascript so bear with me.
I am implementing a tabular Form where the Rows can be Updateable/Not Updateable based on a value of another Field.
The form Displays Quote Lines. The Quote Status is passed from the previous page = DRAFT then lines are updateable else NOT updateable.
I have looked at this post (Thanks to ATD) which is great!
Re: A better method of handling tabular forms with variable column type?
The java script to DISABLE a column based on the value of another Column in the array is as follows(works great):
function disableItems(checkcolumn, columnvalue, disablecolumn)
var f1 = document.getElementsByName(checkcolumn);
var f2 = document.getElementsByName(disablecolumn);
var k;
if (f1)
for (k = 0; k < f1.length; k++)
if (f1[k].value == columnvalue)
f2[k].readOnly = true;
f2[k].style.backgroundColor = 'silver';
Is there a way to reference an item in the page that is NOT in the array.
I have an item which appears in the source as name='p_t01'
var f3 = document.???('p_t01');
Then in the function would be:
if (f3.value = columnvalue)
f2[k].readOnly = true;
II realise this is very javascript - not APEX specific.
Hoe you can help.
Regards
Chris

Answer 1

To get element:
- document.getElementById("element_id")
- using Jquery -> $("#element_id")
- using APEX API funct. -> $x("element_id")
To get value:
- document.getElementById('element_id').value()
- using Jquery -> $("#element_id").val()
- APEX API functions -> $v("element_id")
In most cases element_id is equal to element_name
