如何在动态生成的元素上应用样式

Question

function createList(arrunique, arrayout) {
    for (i = 0; i < arrayout[0].length; i++) {
        var divIdC = i;
        var divIdT = i + 10;

        $('#tb').append('<select name="combo" style="float:left; width:100px;" id="' + divIdC + '" onchange="getComboVal(this,' + divIdC + ')"></select>');
        $('#tb').append('<input type="text" name = "textBox" style= "width:100px;" id="' + divIdT + '" onkeyup="validate(this,"' + divIdT + '") value="0">');
        var select = document.getElementById(divIdC);
        select.options[select.options.length] = new Option("Select " + arrunique[i][0]);
        for (j = 1; j < arrunique[i].length; j++) {
            select.options[select.options.length] = new Option(arrunique[i][j]);
        };
    };
}

In this code I want to generate a combo box and a textbox and I want to apply some style sheet attribute or any class. How can I do this. Its not working.

Answer 1

There are many, many ways of styling a javascript created element. Here are a few. Click here for live demo.

var myElem = document.createElement('div');
myElem.style.color = '#FFF';

with jQuery:

var $myElem = $('<div></div>');
$myElem.css('color', '#FFF');

or jQuery css object syntax (for passing multiple styles)

$myElem.css({display: 'block', background: '#000'});

Rather than adding the style after creating the element, you may also consider just adding a class to the element after creating it and styling this class in your css file.

CSS file:

.myElem {
  color: #FFF;
}


myElem.className = 'myElem';

or

$myElem.addClass('myElem');

Answer 2

$('#tb').append('<input type="text" class="YOURCLASS" name = "textBox" style= "width:100px;" id="'+divIdT+'" onkeyup="validate(this,"'+divIdT+'") value="0">');

See this simplified jsFiddle . Ensure that the console is not generating an errors, and that you're calling the createList() function.
