[待解决问题]

TextBox  ReadOnly属性设置成true以后页面刷新TextBox 的值会消失,

               Enabled 属性也一样,谁有好的解决方案说一下~~多谢各位了~

问题补充: openTab: function(link) { var id = !link.href ? Ext.id() : link.href.replace(/[^A-Z0-9-_]/gi, ''); var tab; var html = '<iframe id="iframe' + id + '" width="100%" src="'; if (link.href.indexOf('?') < 0) { link.href = link.href + "?PageID=" + id + "&PageTitle=" + encodeURI(link.text.replace(/['\&''\?']/gi, '')); } else { link.href = link.href + "&PageID=" + id + "&PageTitle=" + encodeURI(link.text.replace(/['\&''\?']/gi, '')); } //End Add var tabTip = link.text; if (typeof (link.tip) != 'undefined') { tabTip += link.tip; } html = html + link.href; html = html + '" height=100% name="iframe' + id + '" frameborder="0" scrolling="auto" style="border:0px none;" ></iframe>'; if (!(tab = this.getItem(id))) { tab = new Ext.Panel({ id: id, cls: 'preview single-preview', title: link.text, tabTip: tabTip, html: html, closable: true, listeners: AppPortal.LinkInterceptor, autoScroll: true, border: true//, }); this.add(tab); } this.setActiveTab(tab); },

我估计你是这样:

程序本身的ReadOnly不是true,你用程序代码改成了true,Enable也一样。

然后,你刷新了,等于是回到了初始状态

所以,你在程序设置时,在属性中设置成ture or fasle,绝对不会如些。。。

刷新等于重新加载。。。

通过脚本控制ReadOnly或设置Attribute的ReadOnly

我估计你是用 js修改了 readonly=readonly,当postback之后,值是不会提交的,在form中所有input html,如果是disabled或者readonly,都不会post的,所以Server不会更新ViewState的值,postback之后,值就会消失。

有两种解决方法

1) 当 post 的时候,把textbox的Readonly或者Disabled 去除,如 document.forms[0].onsubmit=function(){ $("#textbox").removeAttr("readonly"); return true;} 

2)在Textbox上面加focus事件,当focus到这个Texbox的时候,自动失去焦点。那么相当于readonly

纯js操作刷新之后是保存不了状态的

回楼上,readonly可以提交,disabled不会...
