    javascript - what is the alternate function for indexOf for string in IE8? - Stack Overflow

    programmeradmin4浏览0评论

    I have used indexOf to check whether i have particular text is present in a sentence or not like the following

    var temp = "";
temp="data not available";
if(temp.indexOf("datas") == 0){
    alert("True");
}
else{
    alert("false");
}

    The problem i was facing is indexOf is not supported in Internet Explorer 8. How to perform this operation in IE8 too? Is there any default alternate functions available in jquery?

    I tried inArray but it supports only array.

    Reset to default 14

    I think you're confused about which indexOf() is supported.

    You're using String.prototype.indexOf(), which is supported from IE6 onwards, according to Microsoft's documentation.

    It's Array.prototype.indexOf() that's only supported from IE9 onwards.

    You can use String.search:

    var temp = "data not available";
if(!temp.search("datas")){
    alert("True");
} else {
    alert("false");
}

    Fiddle

    (NB: I don't have IE8 to test it)
