Question

在我的html中,我有2个外部档案。

externalCSSContents = [];

function getExternalCSSContents(){
    var i, href;
    for (i=0; i < document.styleSheets.length; i++)
    {
        href = document.styleSheets[i].href;
            if (href != null)
            {  
                $.ajax({
                    async: false,
                    url: href, 
                    success: function (data) { 
                        externalCSSContents.push(data);
                    }
                });
            }
    }

}
getExternalCSSContents();
alert(externalCSSContents.length);

and this code is sometimes alerting 1 in firefox but permanently 2 in other browsers. What s wrong and how can i solve it?
[Edit] href sometimes = null in ff
[Edit2] I understood, sorry that I didn t mention about prefixfree.min.js attached. And with this library document.styleSheets[i].href was working in FireFox like in Chrome without it. ( document.styleSheets doesn t supported by Сhrome ). Thank you all for your answers and once more sorry for my inattentiveness.

另一名阿富汗复兴共和军受害者。 AJAX支持Asynchronousalle Java和XML。第一部分已在这里(Asynchronous )。

或许,在发出警报之前,AJAX号呼吁尚未结束。当你完成AJAX的职能时,你可以使用一个叫.。

externalCSSContents = [];

function getExternalCSSContents(callback){
    var i, href;
    for (i=0; i < document.styleSheets.length; i++)
    {
        href = document.styleSheets[i].href;
            if (href != null)
            {  
                $.ajax({
                    url: href, 
                    success: function (data) { 
                        externalCSSContents.push(data);
                        callback();
                    }
                });
            }
    }

}
getExternalCSSContents(downloadReady);

function downloadReady() {
    alert(externalCSSContents.length);
}

如果把警示转向成功功能,你可能会有种族条件。你们要警惕,等待阿盟教团的呼吁结束。
