Mutiple element id's

[rhyspaterson]

Hey guys,

 

Just wondering if it is possible to return the value of multiple elements in one command? If that didn't make sense, which it probably doesn't because i'm an idiot, here is an example:

 

Original code is

 

var aText = document.getElementById('textarea1').value;

 

Which works nicely, but looking to return the value of three -

 

var aText = document.getElementById('textarea1', 'textarea2', 'textarea3').value;

 

Which doesn't work obviously. Just not sure how to do it, heh. Any help would be muchly appreciated! Thanks guys

It actually depends on how you named your element's id. Issit in a sequence way? Eg:

textarea1

textarea2

textarea3

textarea4

.... so on....

 

If it is so, you can use loop to look through every elements:

var total_element = 10;

for(var i=1; i<total_element; i++){

    var aText = document.getElementById("textarea" + i).value;

}

you could use the loop and place all the variables in a an array for use later on

 

var elementArray = new Array();
var total_element = 10;
for(var i=1; i<total_element; i++)
{
    elementArray[i-1]= document.getElementById("textarea" + i).value;
}

this is written this way because array all start at 0 --> elementArray[i-1]

Sort of what like paul said... just pass an array of IDs, and have your function decide what to do to get at the elements.
