服务器控件visible与style.visibility

    技术2022-05-11  7

    今天修改项目的时候想通过js来控制一个textbox的显示 ,开始的做法是将textbox.visible = false , 但是

    document.all("textbox")这段js总是显示对象为空的错误,查看网页源代码发现找不到id为textbox的文本框,

    难道是visible 属性的原因吗?我把默认隐藏的方法由visible = false 改为前台

     document.all("txt_Reply").style.visibility = "hidden";之后就好了.

    我查了一下msdn上对两者的解释是:

    visible = true                                                                                                                                  so ASP.NET will generate the html code about the control, if false, no html code about this control will be generated

    style("visibility")="visible"  so the browser will make the control visible on the client side, if "hidden", the control will not be visible on the client side, but the html code is still there
