I am new to JS and I'm running a CMS, I have a dynamic Ids, my concern is, I would to simplify IDs to lessen JS codes by adding arrays of IDs.

Can you guys help me how to simplify this code

    //
    // Id1 = #options_1_text
    // Id2 = #option_2_text
    // Id3 = #option_3_text
    // Id(n) = so on..

    $x1("#options_1_text").miniColors({
        letterCase: 'uppercase',
        change: function (hex, rgb) {
            logData('change', hex, rgb);
        }
    });


    $x1("#options_2_text").miniColors({
        letterCase: 'uppercase',
        change: function (hex, rgb) {
            logData('change', hex, rgb);
        }
    });


    $x1("#options_3_text").miniColors({
        letterCase: 'uppercase',
        change: function (hex, rgb) {

Answer 1

Try this:

$x1(document).ready(function () {
    var ids = [
        "#options_1_text",
        "#options_2_text",
        "#options_3_text",
        "#options_4_text",
        .
        .
        .
        .
        ."#options_n_text",
    ];
    $x1.each(ids, function(i, el){
        $x1(el).miniColors({
            letterCase: 'uppercase',
            change: function (hex, rgb) {
                    logData('change', hex, rgb);
            }
        });

    });

});

If what the code does is really the same for all elements:

 for (var i=1; i<4; i++) {
    $x1("#options_"+i+"_text").miniColors({
                letterCase: 'uppercase',
                change: function(hex, rgb) {
                    logData('change', hex, rgb);
                }
            });
 }

If the ids are not a simple sequence like that

 var ids = [ 'id1', 'another_id', 'one_more' ];

and then loop over that array .

Answer 3

  var str='',n=4;
for (var i=1; i<n; i++) {
    str+=",#options_"+i+"_text";
                         }
 str[0]='';

$x1(str).miniColors({
        letterCase: 'uppercase',
        change: function (hex, rgb) {
            logData('change', hex, rgb);
        }
    });

Answer 4

The simplest way here would be to add a common class to each of these items and let jQuery do all the work for you so you could just do this:

$x1(document).ready(function () {

    $x1(".options_text").miniColors({
        letterCase: 'uppercase',
        change: function (hex, rgb) {
            logData('change', hex, rgb);
        }
    });

});

If you can't modify the HTML, and you can assume that the items are numbered sequentially starting with 1, you could dynamically look for the existing elements:

$x1(document).ready(function () {
    var i = 1, elem;
    while (elem = document.getElementById("options_" + i + "_text")) {
        $x1(elem).miniColors({
             letterCase: 'uppercase',
             change: function (hex, rgb) {
                 logData('change', hex, rgb);
             }
        });
        i++;
    }
});

Answer 5

If it is a simple pattern and you don't know the number n of elements you can do it like this:

var n = 1;
while($('#options_'+n+'_text').length > 0)
{
    $x1('#options_'+n+'_text').miniColors({
        letterCase: 'uppercase',
        change: function (hex, rgb) {
            logData('change', hex, rgb);
        }
    });
    n++;
}

Answer 6

Well, structured one here:

$x1(document)
.ready(function () {
$x1("#options_1_text")
    .miniColors({
    letterCase: "uppercase",
    change: function (a, b) {
        logData("change", a, b)
    }
}), $x1("#options_2_text")
    .miniColors({
    letterCase: "uppercase",
    change: function (a, b) {
        logData("change", a, b)
    }
}), $x1("#options_3_text")
    .miniColors({
    letterCase: "uppercase",
    change: function (a, b) {
        logData("change", a, b)
    }
})
})
