求助,有没有获取页面document或者body高度变化的事件
有个iframe欠套页面,iframe里面的有一个 <textarea style= "overflow-y:visible " />
目的是iframe里面的页面大小改变了,触发iframe的大小改变。有没有一个通用的捕捉页面大小改变的事件。最好是document或body的事件。
------解决方案--------------------就是onload事件.
------解决方案--------------------这里有段抄来的代码,希望对你有用.
function f_frameStyleResize(targObj){
var targWin = targObj.parent.document.all[targObj.name];
if(targWin != null) {
var HeightValue = targObj.document.body.scrollHeight
if(HeightValue < 400){HeightValue = 400}
targWin.style.pixelHeight = HeightValue;
}
}
function f_iframeResize(){
bLoadComplete = true; f_frameStyleResize(self);
}
var bLoadComplete = false;
window.onload = f_iframeResize;
这段代码的意思是根据iframe的高度,自动调整父窗口中iframe的高度,让iframe全显示出来.
------解决方案--------------------onresize

------解决方案--------------------onload也要:
<body onresize= "alert( 'bodyResize: ' + this.scrollHeight) ">
---> > >
<body onresize= "alert( 'bodyResize: ' + this.scrollHeight) " onload= "alert( 'bodyResize: ' + this.scrollHeight) ">
------解决方案--------------------body是没有onresize事件地...
