Question

I have an array with the following when console.log(cMentions):

Object
41: "Never Ever"
43: "Steve Jobs"
55: "Henry Ford"
__proto__: Object

Then I have a textarea(id=”comment”) with:

Hello @Steve Jobs @Never Ever and friends

What I want to do is determine if the cMentions record are in the textarea value. If they are do X, if they are not do Y.

Use case. When this runs, it would notice that Henry Ford is not in the textarea and would remove it.

Ideas?

Thanks

Loop through each element, and check whether the name at the key exists in the string, using .indexOf:

//cMentions is defined as in the question
var commentValue = $('#comment').val();
for (var id in cMentions) {
    if (cMentions.hasOwnProperty(id)) { // Ignore native methods
        var searchTerm = cMentions[id]; // Search for the existence of this name
        if (commentValue.indexOf(searchTerm) == -1) {
            cMentions[id] = void 0;     // Overwriting by `void 0` = `undefined`
            delete cMentions[id];       // In case the variable still exists
        }
    }
}
