How to Disable whole Div Contents without using JQuery

Question

As I have Basic knowledge of JavaScript I want to do operation like following :

• By using Two radio button giving two option for Payment :

  1. By Cash
  2. By Check

• If user select the radio button of Cash the Cheque Button should also disable and the Div of Cheque in which the details like cheque no and bank name is should also disable.

• And visa Versa

Is there a way to do that without using JQuery? (disable a div and get all content disabled also)

Thanks in Advance For Help.

Answer 1

Try this:

document.getElementById("myDivId").disabled = true;

To disable all elements inside the div, try this:

var allChildNodes = document.getElementById("myDivId").getElementsByTagName('*');

for(var i = 0; i < allChildNodes.length; i++)
{
   allChildNodes[i].disabled = true;
}

Answer 2

This code will disable all elements within the given container.

var container = document.getElementById("cashContainer");
var inputs = document.getElementsByTagName("input").concat(document.getElementsByTagName("select"));
for (var i = 0; i < inputs.length; i++) {
    inputs[i].disabled = true;
}

Applying the same code you can re-enable the other container.

HTML

<input type="radio" name="cashcheck" value="cash" checked />Cash<br />
<div id="cash">
    <form method="post">
        <input type="text" name="cashTxt1" />
        <input type="text" name="cashTxt2" />
    </form>
</div>

<input type="radio" name="cashcheck" value="check" />Check<br />
<div id="check">
    <form method="post">
        <input type="text" name="checkTxt1" disabled />
        <input type="text" name="checkTxt2" disabled />
    </form>
</div>

JS

window.onload=function(){
    var radios = document.getElementsByName('cashcheck');
    radios[0].onchange=toggle;
    radios[1].onchange=toggle;
};

function toggle()
{
    if(this.checked)
    {
        var div = document.getElementById(this.value),
        inputs = div.getElementsByTagName('form')[0].getElementsByTagName('*');
        for( var i=0; i<inputs.length; i++)
        {
            inputs[i].removeAttribute('disabled');
        }

        var op = this.value == 'cash' ? 'check' : 'cash',
        divOp = document.getElementById(op),
        divOpInputs = divOp.getElementsByTagName('form')[0].getElementsByTagName('*');
        for( var i=0; i<divOpInputs.length; i++)
        {
            divOpInputs[i].setAttribute('disabled');
        }
    }
