最后更新时间：2008-04-15 关键字: ie报语法错误
我有两个页面，一个extlogin.jsp输入用户名和密码后经过后台验证跳转到extindex.jsp，但是在点击登陆提交FormPanel 后调试器报出一个语法错误，在ext-all.js的23行，我很难确定它想要说到底是哪里的语法有问题，以下是ext-all.js23行的源代码， 谢谢各位帮忙看看，这两个jsp在FireFox下是不会报错的，没有问题，在IE7下就会报这样的语法错误。 {width:w||this.getWidth(true),height:h||this.getHeight(true)}},getViewSize:function(){var d=this.dom,doc=document,aw=0,ah=0;if(d==doc||d==doc.body){return{width:D.getViewWidth(),height:D.getViewHeight()}}else{return{width:d.clientWidth,height:d.clientHeight}}},getValue:function(asNumber){return asNumber?parseInt(this.dom.value,10):this.dom.value},adjustWidth:function(width){if(typeof width=="number"){if(this.autoBoxAdjust&&!this.isBorderBox()){width-=(this.getBorderWidth("lr")+this.getPadding("lr"))}if(width<0){width=0}}return width},adjustHeight:function(height){if(typeof height=="number"){if(this.autoBoxAdjust&&!this.isBorderBox()){height-=(this.getBorderWidth("tb")+this.getPadding("tb"))}if(height<0){height=0}}return height},setWidth:function(width,animate){width=this.adjustWidth(width);if(!animate||!A){this.dom.style.width=this.addUnits(width)}else{this.anim({width:{to:width}},this.preanim(arguments,1))}return this},setHeight:function(height,animate){height=this.adjustHeight(height);if(!animate||!A){this.dom.style.height=this.addUnits(height)}else{this.anim({height:{to:height}},this.preanim(arguments,1))}return this},setSize:function(width,height,animate){if(typeof width=="object"){height=width.height;width=width.width}width=this.adjustWidth(width);height=this.adjustHeight(height);if(!animate||!A){this.dom.style.width=this.addUnits(width);this.dom.style.height=this.addUnits(height)}else{this.anim({width:{to:width},height:{to:height}},this.preanim(arguments,2))}return this},setBounds:function(x,y,width,height,animate){if(!animate||!A){this.setSize(width,height);this.setLocation(x,y)}else{width=this.adjustWidth(width);height=this.adjustHeight(height);this.anim({points:{to:[x,y]},width:{to:width},height:{to:height}},this.preanim(arguments,4),"motion")}return this},setRegion:function(region,animate){this.setBounds(region.left,region.top,region.right-region.left,region.bottom-region.top,this.preanim(arguments,1));return this},addListener:function(eventName,fn,scope,options){Ext.EventManager.on(this.dom,eventName,fn,scope||this,options)},removeListener:function(eventName,fn){Ext.EventManager.removeListener(this.dom,eventName,fn);return this},removeAllListeners:function(){E.purgeElement(this.dom);return this},relayEvent:function(eventName,observable){this.on(eventName,function(e){observable.fireEvent(eventName,e)})},setOpacity:function(opacity,animate){if(!animate||!A){var s=this.dom.style;if(Ext.isIE){s.zoom=1;s.filter=(s.filter||"").replace(/alpha\([^\)]*\)/gi,"")+(opacity==1?"":" alpha(opacity="+opacity*100+")")}else{s.opacity=opacity}}else{this.anim({opacity:{to:opacity}},this.preanim(arguments,1),null,0.35,"easeIn")}return this},getLeft:function(local){if(!local){return this.getX()}else{return parseInt(this.getStyle("left"),10)||0}},getRight:function(local){if(!local){return this.getX()+this.getWidth()}else{return(this.getLeft(true)+this.getWidth())||0}},getTop:function(local){if(!local){return this.getY()}else{return parseInt(this.getStyle("top"),10)||0}},getBottom:function(local){if(!local){return this.getY()+this.getHeight()}else{return(this.getTop(true)+this.getHeight())||0}},position:function(pos,zIndex,x,y){if(!pos){if(this.getStyle("position")=="static"){this.setStyle("position","relative")}}else{this.setStyle("position",pos)}if(zIndex){this.setStyle("z-index",zIndex)}if(x!==undefined&&y!==undefined){this.setXY([x,y])}else{if(x!==undefined){this.setX(x)}else{if(y!==undefined){this.setY(y)}}}},clearPositioning:function(value)

我也碰到一个脚本错误，和楼主差不多，报的是参数无效，跟了一下是width得到一个NaN的值，在ext-all-debug.js 的这段中的这行报错：
行：this.dom.style.width = this.addUnits(width); 段：setWidth : function(width, animate){ width = this.adjustWidth(width); if(!animate || !A){ this.dom.style.width = this.addUnits(width); }else{ this.anim({width: {to: width}}, this.preanim(arguments, 1)); } return this; }, |

老大，最后怎么解决的呀，我也是遇到这样的问题，在TeePanel的click事件中，不能使用Ext.Message.confirm和Ext.window，不然，就关闭弹出的窗口后，就报"无效参数"。
如下图中，点击logout后，弹出确认框，这里都没有问题，但无论是点YES还是No,都报错"无效参数"。

我也遇到这个问题 ，主要解决是nan的问题，我的主要产生nan的问题是panel.height 这个属性得到nan 我最后使用panel.getSize()['height'] 来获得高度
