    javascript - change margin-left with JS - Stack Overflow

    programmeradmin5浏览0评论

    I want a dynamical margin-left on a given div.

    I tried this code :

    window.onload = function()
{
    var pageWidth = window.innerWidth; 
    var size = (pageWidth - 200 ) / 2;
    $('#search').css('margin-Left', size));
    alert(size);
 };

    which doesn't work (the alert is here just for test purpose), the problem is ing from the ligne $('#search').css('margin-Left', size)); but I can't find out where...

    I've tried with a lowercase l on margin-left and didn't work.

    • 2 $('#search').css('margin-left', size)); case sensitive – Harsha Venkataramu Commented Oct 17, 2013 at 19:06
    • @harsha already tried, didn't work either. – Thomas Ayoub Commented Oct 17, 2013 at 19:08
    • Are you sure the div has an id of 'search' and not a class? – Andrew Commented Oct 17, 2013 at 19:09
    • If you inspect the div with the developer tools for your browser is there an inline style there? – Andrew Commented Oct 17, 2013 at 19:10
    • 3 You should note that you have an extra closing parenthesis on your code. – Giovanni Silveira Commented Oct 17, 2013 at 19:25

    Reset to default 8

    Would the following work for you?

    document.getElementById("search").style.marginLeft = size + "px";

    You need to specify the type of unit you want to use.

    $('#search').css('margin-left', size + 'px');

    Try using marginLeft, without the hypen.

    jQuery.css() documentation: http://api.jquery./css/

    JAVASCRIPT

    $(document).ready(function(e){
    alert('test');
    var pageWidth = parseInt($(window).innerWidth());
    alert(pageWidth);
    var size = (pageWidth - 200 ) / 2;
    $('#search').css('margin-left', size);
    alert(size);
})

    HTML

    <div id = 'search'></div>

    CSS

    #search
{
    height:100px;
    width:100px;
    background-color:#F00;
}
