jQuery/JavaScript operator equal SQL LIKE %Example%

Question

Is there any way to search a specific part on my input with Javascript/jQuery?

Tried to do with 2 different ways, but no results for that

<script type="text/javascript">
$("#button").click(function () {

    $("#DivToToggle").toggle();
    var campo = document.getElementById('FieldToSearch');

    if (campo.contains("Test")) {
        document.getElementById('FieldToWrite').value = "123";
    }
    else {
        document.getElementById('FieldToWrite').value = "456";
    }
});

and

<script type="text/javascript">
$("#button").click(function () {

    $("#DivToToggle").toggle();
    var field = document.getElementById('FieldToSearch');

    if (field.match(/Test.*/)) {
        document.getElementById('FieldToWrite').value = "123";
    }
    else {
        document.getElementById('FieldToWrite').value = "456";
    }
});

@EDIT

Thanks to @TalhaAbrar, found the correct way to do it.

<script type="text/javascript">
$("#button").click(function () {


    var field = document.getElementById('FieldToSearch').value;

    if (field.indexOf("Test")) {
        $("#DivToToggle").toggle();
        document.getElementById('FieldToWrite').value = "123";
    }
    else {
        $("#DivToToggle").toggle();
        document.getElementById('FieldToWrite').value = "456";
    }
});

The problem is `FieldToSearch` is an HTML element - did you want the `text` property of it? — tymeJV, Jul 18 '19 at 14:44

@TalhaAbrar not really. That's about arrays, not Element objects — Rory McCrossan, Jul 18 '19 at 14:46
@tymeJV Yes, i want to search some text in this input. If have, do something. Else, do another thing — Hudson Medeiros, Jul 18 '19 at 14:49
You need the `value` of that element when it is a form control — charlietfl, Jul 18 '19 at 14:50
@HudsonMedeiros Try to fetch the value of search field like `document.getElementById('FieldToSearch').value` and then use function `indexOf` in your if statement, that should work for you. — Talha Abrar, Jul 18 '19 at 14:58
Thanks to @TalhaAbrar! It works like a charm. Edited main post with functional code. — Hudson Medeiros, Jul 18 '19 at 15:13

I think you need to check the value of the field, e.g.

var campo = document.getElementById('FieldToSearch').value;
...

And then use includes(), e.g.

if (campo.includes("Test")) {
...

It writes the "else" (456) option to FildToWrite – Hudson Medeiros Jul 18 '19 at 14:59
So what is the value of `campo`? – Rory McCrossan Jul 18 '19 at 15:01
It should be the value of the html `` element with the id `FieldToSearch`. @HudsonMedeiros can you show your HTML in your question? – Chris Wheeler Jul 19 '19 at 13:20

Try to fetch the value of search field like document.getElementById('FieldToSearch').value and then use function indexOf in your if statement, that should work for you.

example code:

var field = document.getElementById('FieldToSearch').value;

if (field.indexOf("value_to_check")) {
    // true if exists
} else {
    // false if doesn't
}
