Search table with filter in Jquery

This is my code:

function search() {
    $("#myInput").keyup(function () {
        var value = this.value;

        $("table").find("tr").each(function (index) {
            if (index === 0) return;
            var id = $(this).find("td").first().text();
            $(this).toggle(id.indexOf(value) !== -1);
        });
    });
}

$('body').on('click', '#searchFonts', function () {
    var value = "Font"
    $("table").find("tr").each(function (index) {
        if (index === 0) return;
        var id = $(this).find("td").first().text();
        $(this).toggle(id.indexOf(value) !== -1);
    });
});

$('body').on('click', '#searchScripts ', function () {
    var value = "script"
    $("table").find("tr").each(function (index) {
        if (index === 0) return;
        var id = $(this).find("td").first().text();
        $(this).toggle(id.indexOf(value) !== -1);
    });
});

I’m looking for ways to make this run more effectively, as I’m sure there is a more efficient way to search for the specific value’s seen below such as ‘Font’ and ‘Script’.

D.R.Y.

There is a widely accepted principle amongst developers: Don’t Repeat Yourself. The following block appears three times (with varying spacing):

$("table").find("tr").each(function(index) {
    if (index === 0) return;
    var id = $(this).find("td").first().text();
    $(this).toggle(id.indexOf(value) !== -1);
});

That can be abstracted into a function (which could accept a parameter for the value) which could then be called in place of that repeated block.

For example:

function toggleRowsWithKeyword(value) { 
    $("table").find("tr").each(function(index) {
        if (index === 0) return;
        var id = $(this).find("td").first().text();
        $(this).toggle(id.indexOf(value) !== -1);
    });
}

And usage:

function search() {
  $("#myInput").keyup(function() {
      toggleRowsWithKeyword(this.value);        
  });
}
$('body').on('click','#searchFonts',function(){
    toggleRowsWithKeyword("Font");
});
$('body').on('click','#searchScripts ',function(){
    toggleRowsWithKeyword("script");
});

Cache DOM lookups

Even with abstracting that code into a function, it would still be performing a query on the DOM.

$("table").find("tr")

That can be stored in a variable (or constant if ES-6’s const is used):

var rows = $("table").find("tr");

To be on the safe side, that assignment can be placed inside a DOM-loaded callback (e.g. a function wrapped to the jQuery callback wrapper: $()):

$(function() {  //DOM is ready
    var rows = $("table").find("tr");
    //Define  toggleRowsWithKeyword(), add click handlers, etc.
}); 

Then the function can utilize rows instead of querying for the rows:

rows.each(function(index) {...

CSS Selector for all except first row

The CSS Selector:

var rows = $("table").find("tr")

Could be simplified to:

var rows = $("tr")

And the check for the first row (i.e. if (index === 0) return;) could be eliminated using the :not pseudo-class along with :first-child:

var rows =  $("tr:not(:first-child)")
