Question

我有某些法典,我试图在文字档案中添加文字档案,然后在文字档案中打电话。该守则是:

function includeJS(p_file) {
    var v_js  = document.createElement( script );
    v_js.type =  text/javascript ;
    v_js.src = p_file;
    document.getElementsByTagName( head )[0].appendChild(v_js);
}

function checkFlash(){
    includeJS( /scripts/swfobject.js );
    var playerVersion = swfobject.getFlashPlayerVersion();
    return playerVersion.major;
}

alert(checkFlash());

问题在于它试图获得参与者版本的盘点。我检查了大火,这显示文字被装上,读书正确无误,因此它不是一个道路问题。

I thought that maybe it was a delay issue in the includeJS function, but when I would that code in before the alert without it being a function, it still gives the same problem.

关于我如何做这样的事情的想法?

感谢。

我认为,你的问题是,在你试图检查角色版本之前,文字档案没有完成装货(与你原先想象的一样)。您不妨尝试:

function includeJS(p_file, callback) {
    var v_js  = document.createElement( script );
    v_js.type =  text/javascript ;
    v_js.src = p_file;

    v_js.onreadystatechange = callback;
    v_js.onload = callback;

    document.getElementsByTagName( head )[0].appendChild(v_js);
}

function checkFlash(){
    var playerVersion;
    includeJS( /scripts/swfobject.js , function () {
        var playerVersion = swfobject.getFlashPlayerVersion();
        alert(playerVersion.major);
    });
}

checkFlash();

这是对similar问题的答复中提出的解决办法。
