Javascript window.find alternative for internet explorer?

Question

i want to implement the javascript function of window.find(). but it is not working in internet explorer. what could be an alternative for this code ?

Answer 1

To achieve browser compatibility use

function windowFind(str){
    if("find" in window){
         return window.find(str);
    }else{
         return document.getElementsByTagName("body").innerHTML.indexOf(str) > -1;
    }
}

This method is called feature detection and is used in many javascript libraries to achieve browser compatibility.

Answer 2

try this

function contains(strs) {
    return document.body.innerText.indexOf(strs) > -1;
}
