How do i ensure that my textarea value should always contain the word "india" in javascript?

Actually i want to validate the textarea so that the user should always the word "india" in that.

Please help me. Thanks in advance.

Answer 1

You can use the blur event which is invoked when the user removes focus from the textarea.

<textarea onblur="return validate(this);"></textarea>

var reg = /\bindia\b/im;
function validate(textArea) {
    // case-insensitive search for "india"
    if (!reg.test(textArea.value)) {
        alert("Where's India?");
    }
}

Answer 2

do you mean when the page loads to have the word 'India' in your textarea and it can be written over? or do you want it there permanent?

Answer 3

<textarea onchange='if(this.value.indexOf("india") == -1) this.value = "";'></textarea>
