如何从javascript填充文本框值并执行剩余的代码 [英] How can I fill textbox value from javascript and execute the remaining code

问题描述

大家好我已经编写了一个javascript函数，我从代码后面传递3个参数我在文本框上留下了一个文本框，按钮和一个文本框，当光标位于第一个文本内时单击按钮框我想填写脚本中的第二个文本框我在按钮内调用脚本如下

 <   script     type   =  text / javascript  >  
功能getEndDate2（noOfWeeks，sEmployeeWeeklyOfDay，DateStart）{
 //我的脚本代码
} 
 
 <跨度类=代码关键字><   asp：TextBox     ID   =  txtString    runat   = 服务器 >  <   / asp：TextBox  >  
 <   br     /  >  
 <   asp：TextBox     ID   =  TextBox1    runat   =  server >  <   / asp：TextBox  >  
 
 <   asp：按钮    ID   =  btnClick    runat   =  server   文本  = 传递    OnClick   =  btnClick_Click    /  >  
 
 protected void btnClick_Cl ick（object sender，EventArgs e）
 {
 int noOfweeks = Convert.ToInt16（txtString.Text）;; 
 string sEmployeeWeeklyOfDay =Friday; 
 string DateStart = DateTime.Now.AddDays（3）.ToString（）; 
 btnClick.Attributes.Add（ 的onClick， getEndDate2（ ' + noOfweeks +  '' + sEmployeeWeeklyOfDay +  '' + DateStart + '）;）; 
 //将值插入数据库的一些代码
} 

但无法显示值第二个文本框可以帮助我如何调用该脚本后立即从文本框中丢失焦点或任何方法首先填充文本框

解决方案

为什么不要在OnClientClick按钮上调用它，因为你也可以用javascript做同样的事情......

例如

功能getEndDate2（）
 {
 <跨度类= 代码关键字> VAR  noOfweeks =的document.getElementById（<跨度类= 代码串>' < span class =code-string> txtString'）。innerHTML; 
 <跨度类= 代码关键字> VAR  sEmployeeWeeklyOfDay = <跨度类= 代码串>  <跨度类= 代码串 >星期五; 
  var  DateStart =  new  Date（）; 
 DateStart.setDate（DateStart.getDate（）+ 3）; 
的document.getElementById（<跨度类= 代码串> ' <跨度类= 代码串> TextBox1的'）。<跨度类= 代码sdkkeyword > value  = DateStart.getDate（）; 
  //  我的脚本代码 
} 

 <   asp：button     id   =  btnClick    runat   =   server    text  < span class =code-keyword> = 传递    onclientclick   =  getEndDate2（）    xmlns：asp   = ＃unknown    /  > ;  

Hi all I have written a javascript function where I pass 3 arguments from code behind I am having a text box, button and a text box on my form on leaving text box or clicking the button when the cursor is inside the first text box I would like to fill the second text box from the script I call the script inside the button as follows

<script type="text/javascript">
    function getEndDate2(noOfWeeks, sEmployeeWeeklyOfDay, DateStart) {
            // My script code
  }

<asp:TextBox ID="txtString" runat="server"></asp:TextBox>
<br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

 <asp:Button ID="btnClick" runat="server" Text="Pass" OnClick="btnClick_Click" />

protected void btnClick_Click(object sender, EventArgs e)
{
    int noOfweeks = Convert.ToInt16(txtString.Text);;
    string sEmployeeWeeklyOfDay = "Friday";
    string DateStart = DateTime.Now.AddDays(3).ToString();
    btnClick.Attributes.Add("onClick", "getEndDate2('" + noOfweeks + "','" + sEmployeeWeeklyOfDay + "','" + DateStart + "');");
     // Some code to insert the values to database
 }

But unable to display the value in the second text box can some one help me how can I call that script Immediately after losing focus on from the text box or any method to fill the text box first

解决方案

why don''t u call it on OnClientClick of button because u can able to do same thing from javascript also...
for example

function getEndDate2()
    {
    var noOfweeks = document.getElementById('txtString').innerHTML ;
    var sEmployeeWeeklyOfDay = "Friday";
    var DateStart = new Date();
    DateStart.setDate(DateStart.getDate()+3);
    document.getElementById('TextBox1').value = DateStart.getDate();
    // My script code
    }

<asp:button id="btnClick" runat="server" text="Pass" onclientclick="getEndDate2()" xmlns:asp="#unknown" />
