Jquery Search Word In String

I have html content where some words have success, failure etc. I am trying to use a regular expression to filter with single keyword or combination of keywords from multi selectio

Solution 1:

Let me just say that using regexes for this may be a bit of a solution looking for a problem and you might get much further using plain .indexOf() or the like as in @RIYAJ KHAN’s answer…

If you have an array with all the words you’re looking for, for example:

var WORDS = ['success', 'failure'];

you can create your RegExp object as follows:

var expression = new RegExp('\\b('+WORDS.join('|')+')\\b');

(Using \b at beginning and end will ensure you only match whole words, which may be the only valid reason to use a regex for this.)

Note that JavaScript does not have a function to escape regex special characters from strings but if you don’t know whether your strings are regex-safe or not, use this to escape the array items first.

Then search for any word:

var found = expression.test($(this).text());

Note that if you want to find out which words matched, you’d have to use the String.prototype.match method instead of String.prototype.search.

Solution 2:

Define one array containig your expected string

var arrString = ["success","failure"];

As you say,multi selection checkboxes is a comma separated string.

So, I am assuming like this.

var arrHtml = "success,test,test2,failure";  ////$(this).html()
arrHtml.split(",").some(function(val, index) {
    return arrString.indexOf(val) >= 0
})

OR ECMA6 :

arrHtml.split(",").some((val,index)=> arrString.indexOf(val)>=0 )

Solution 3:

try

var filter = '(success)|(failure)';
$(this).html().search(newRegExp(filter, "i")) > 0) {
alert('data found')
}
