完全跨浏览器测试的脚本:
var CFLoad = {
fScript : null,
isFileReady : function ( v ) {
return ( ! v || v == "loaded" || v == "complete" || v == "uninitialized" );
},
js : function(src,cb,attrs) {
var s = document.createElement( "script" ),
done = !1, i;
s.src = src;
s.type = "text/javascript";
for ( i in attrs ) {
s.setAttribute( i, attrs[ i ] );
}
s.onreadystatechange = s.onload = function () {
if ( ! done && CFLoad.isFileReady( s.readyState ) ) {
done = !0;
if(cb) cb(s);
s.onload = s.onreadystatechange = null;
}
};
window.setTimeout(function() {
if( !done) {
done = !0;
if(cb) cb(s,1);
}
}, 5000);
if(this.fScript===null) this.init();
this.fScript.parentNode.insertBefore( s, this.fScript );
},
css : function(href,cb,attrs) {
var l = document.createElement("link"),i;
l.href = href;
l.rel = "stylesheet";
l.type = "text/css";
for ( i in attrs ) {
l.setAttribute( i, attrs[i]);
}
if(this.fScript===null) this.init();
this.fScript.parentNode.insertBefore(l,this.fScript);
if(cb) window.setTimeout(cb, 0);
},
init : function() {
this.fScript = document.getElementsByTagName( "script" )[ 0 ];
}
};
用法
CFLoad.js("http://code.jquery.com/jquery-1.8.3.js", function (script_tag, failed) {
if(!failed) {
CFLoad.js("http://code.jquery.com/ui/1.9.2/jquery-ui.js", function(s, f) {
if(!f) {
alert("Loaded");
js13 = jQuery.noConflict(true);
main();
}
})
}
});
在你的情况下:
CFLoad.js("playlistcontent.jsonp");
