    javascript - Why won't .getPropertyValue() return a value for the "borderRadius" property? - Stack Ove

    programmeradmin4浏览0评论

    Here is the function:

    function lastmenuborder() {
    var articleparent = document.getElementById('article').parentNode;
    var articlestyle = window.getComputedStyle(articleparent,null).getPropertyValue('borderRadius');
    alert (articlestyle);
}

    I get no value, yet the css for the parent node is:

    div#mainbody div.placeholder {
    border-radius: 3px;
}

    What would I have to change to return "3px"? All help greatly appreciated; I am still a newb at JavaScript.

    • could you check this please? alert(articleparent.style.borderRadius); – Sebas Commented May 29, 2012 at 16:24
    • @Sebas I get no value. Does this mean that I've not referenced the right element? – WK_of_Angmar Commented May 29, 2012 at 16:30
    • If my interpretation of the CSS is correct, it looks like the div.placeholder is getting the border radius styling not, it's parent div#mainbody... this could be why – pandavenger Commented May 29, 2012 at 17:00
    • Are you sure? According to my browser's element inspector, div.placeholder has the style. And CSS applies to the last element in the list. – WK_of_Angmar Commented May 29, 2012 at 17:04

    Reset to default 12

    For getPropertyValue(), you use hyphens instead of camelCase.

    This works in Chrome...

    .getPropertyValue('border-radius');

    But Firefox seems to require specific corners using this syntax...

    .getPropertyValue('border-top-left-radius');

    getComputedStyle is not supported on IE8 below, to fix this use:

    if (!window.getComputedStyle) {
       window.getComputedStyle = function(el, pseudo) {
           this.el = el;
               this.getPropertyValue = function(prop) {
               var re = /(\-([a-z]){1})/g;
               if (prop == 'float') prop = 'styleFloat';
               if (re.test(prop)) {
                   prop = prop.replace(re, function () {
                       return arguments[2].toUpperCase();
                   });
               }
               return el.currentStyle[prop] ? el.currentStyle[prop] : null;
           }
           return this;
       }
   }

var elem = window.getComputedStyle(document.getElementById('test'), "");
alert(elem.getPropertyValue("borderRadius"));
