刚写的Jq带数字显示的进度条插件。使用简单方便。大小，颜色，字体等等参数也可以随时设置。

源代码：

var BlackProgress={
	ProgressWidth:500,
	ProgressHeight:20,
	ProgressParent:null,
	ProgressValue:0,
	ProgressMaxValue:100,
	ProgressStation:null,
	ProgressTrack:null,
	ProgressText:"0%",
	ProgressStationText:null,
	ProgressTextColor:"#f13742",
	ProgressTrackBgColor:"#808080",
	Initialize:function(){
		var ProgressBody=$("");
		var ProgressMain=$("");
		var ProgressBar=$("");
		var ProgressStationMain=$("");
		BlackProgress.ProgressStationText=$("dfd");
		BlackProgress.ProgressStation=$("");
		BlackProgress.ProgressTrack=$("");
		ProgressBody.css({"background-color":"#efefef","width":BlackProgress.ProgressWidth "px","height":BlackProgress.ProgressHeight "px","margin":"0 auto","-webkit-border-radius": "3px","-moz-border-radius": "3px","border-radius": "3px"});
		ProgressBody.attr("id","progressBody");
		$(BlackProgress.ProgressParent).append(ProgressBody);
		//设置ProgressMain
		ProgressMain.css({"background-color":"#34393e","width":BlackProgress.ProgressWidth "px","height":BlackProgress.ProgressHeight-10 "px","margin":"0 auto","margin-top":"4px","-webkit-border-radius": "2em","-moz-border-radius": "2em","border-radius": "2em"});
	    ProgressBody.append(ProgressMain);
		//设置ProgressStationMain
		ProgressStationMain.attr("id","progressStationMain");
		ProgressStationMain.css({"overflow":"hidden","height":(BlackProgress.ProgressHeight-5)*2 "px","width":(BlackProgress.ProgressHeight-5)*2 "px","background-color":"#34393e","position":"absolute","-webkit-border-radius": "50%","-moz-border-radius": "50%","border-radius": "50%","margin-top":-BlackProgress.ProgressHeight 5 (BlackProgress.ProgressHeight-10)/2 "px","margin-left":BlackProgress.ProgressWidth/2-(BlackProgress.ProgressHeight-10) "px"});
		ProgressMain.append(ProgressStationMain);
		//设置ProgressStation
		BlackProgress.ProgressStation.css({"position":"absolute","height":(BlackProgress.ProgressHeight-5)*2 "px","width":(BlackProgress.ProgressHeight-5)*2 "px","-webkit-border-radius": "50% 0 0 50%","-moz-border-radius": "50% 0 0 50%","border-radius": "50% 0 0 50%","background-color":BlackProgress.ProgressTrackBgColor,"margin-left":-(BlackProgress.ProgressHeight-5)*2 "px"});
		ProgressStationMain.append(BlackProgress.ProgressStation);
		//设置ProgressText
		BlackProgress.ProgressStationText.css({"font-size":"12px","position":"absolute","left":(BlackProgress.ProgressHeight-5)*2/2-10 "px","top":(BlackProgress.ProgressHeight-5)*2/2-8 "px","z-index":"999","color":BlackProgress.ProgressTextColor});
		BlackProgress.ProgressStationText.html(BlackProgress.ProgressText);
		ProgressStationMain.append(BlackProgress.ProgressStationText);
		//设置ProgressTrack
		BlackProgress.ProgressTrack.css({"background-color":BlackProgress.ProgressTrackBgColor,"width":"0px","height":BlackProgress.ProgressHeight-10 "px","-webkit-border-radius": "2em","-moz-border-radius": "2em","border-radius": "2em"});
        ProgressMain.append(BlackProgress.ProgressTrack);
		BlackProgress.Value(BlackProgress.ProgressValue);
	},
	Value:function(a){
		if(BlackProgress.ProgressTrack==null||a>=BlackProgress.ProgressMaxValue){
			BlackProgress.ProgressTrack.css("width",BlackProgress.ProgressWidth "px");
			BlackProgress.ProgressStationText.html("100%");
			return;
		}
		BlackProgress.ProgressStationText.html(a/BlackProgress.ProgressMaxValue*100 "%");
		BlackProgress.ProgressTrack.css("width",a/BlackProgress.ProgressMaxValue*BlackProgress.ProgressWidth "px");
		if(a/BlackProgress.ProgressMaxValue*BlackProgress.ProgressWidth>(BlackProgress.ProgressWidth/2-(BlackProgress.ProgressHeight-10))){
			if(a/BlackProgress.ProgressMaxValue*BlackProgress.ProgressWidth-BlackProgress.ProgressWidth/2-(BlackProgress.ProgressHeight-10)>=(BlackProgress.ProgressHeight-5)*2-10)
			{
				$("#progressStationMain").css("background-color",BlackProgress.ProgressTrackBgColor);
				BlackProgress.ProgressStation.css("display","none");
			}
			else
			BlackProgress.ProgressStation.css("margin-left",-(BlackProgress.ProgressHeight-5)*2 a/BlackProgress.ProgressMaxValue*BlackProgress.ProgressWidth-BlackProgress.ProgressWidth/2 "px");
		}
	}
}

使用：

BlackProgress.ProgressParent=$(document.body);
	BlackProgress.Initialize();
	var index=0;
	var mProgressTimer=setInterval(function(){
				index  ;
				BlackProgress.Value(index);
				},50);
