ASP文本框控件占位符属性不会在Internet Explorer中 [英] ASP Textbox control placeholder property doesn't work in Internet Explorer

问题描述

我用兑现从 materializecss.com 的框架。为文本框的占位符不工作的IE浏览器，我认为框架有一些与此有关，因为从我的其他网页我用引导框架尝试，并在占位符的财产的工作，有什么解决办法对我来说，使占位符的兑现框架的物业工作？

 ＆LT; D​​IV CLASS =行＆GT;
  ＆LT; D​​IV CLASS =输入场山坳S10＆GT;
     ＆LT; ASP：文本框ID =txtCompany=服务器可见=假占位符=公司名称＆GT;＆LT; / ASP：文本框＆GT;
   ＆LT; / DIV＆GT;
  ＆LT; D​​IV CLASS =输入场山坳S2＆GT;
     ＆LT; ASP：按钮的ID =btnSave=​​服务器文本=保存的CssClass =BTN波效应波红的OnClick =btnSave_Click可见=假/＆GT;
  ＆LT; / DIV＆GT;
＆LT; / DIV＆GT;
 

解决方案

您需要添加的onfocus 和的onblur 在文本框属性在其工作的Internet Explorer

在这里你去

 ＆LT; D​​IV CLASS =输入场山坳S10＆GT;
    ＆LT; ASP：文本框ID =txtCompany=服务器值=公司名称占位符=公司名称的onfocus =如果（THIS.VALUE == this.defaultValue）THIS.VALUE ='';的onblur =如果（THIS.VALUE ==''）THIS.VALUE = this.defaultValue;＆GT;＆LT; / ASP：文本框＆GT;
＆LT; / DIV＆GT;
 

I'm using the framework of Materialize from materializecss.com. The placeholder for the textbox isn't working on IE, I think the framework has something to do with this because from my other page I tried using bootstrap framework, and the placeholder property worked, is there any solution for me to make the placeholder property work on the Materialize framework?

<div class="row">
  <div class="input-field col s10">
     <asp:TextBox ID="txtCompany" runat="server" Visible="false" placeholder="Company Name" ></asp:TextBox>                  
   </div>
  <div class="input-field col s2">
     <asp:Button ID="btnSave" runat="server" Text="Save" CssClass="btn waves-effect waves-red" OnClick="btnSave_Click" Visible="false" />
  </div>
</div>

解决方案

You need to add onfocus and onblur property in your textbox for working it in Internet Explorer

Here you go

<div class="input-field col s10">
    <asp:TextBox ID="txtCompany" runat="server" value="Company Name" placeholder="Company Name" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;"></asp:TextBox>
</div>
