如何将焦点设置为webForm的控件 [英] How to set Focus to the Controls of webForm

问题描述

代码：

Code:

else if (answer is HandwrittenAnswer)
{
  this.Sourcecode.AppendLine("\t\t\t\t<textarea id='" + id + "' name='" + id + "' value='' style='position: absolute; "
                                                         + "top: " + top + "px; left: " + left + "px; height: " + height + "px; width: " + width + "px; "
                                                         + "visibility: hidden; z-index: 2; resize: none;'></textarea>");
  this.Sourcecode.AppendLine("\t\t\t\tdocument.getElementById (" + id + ").focus();");
  
}

上面的代码，当我点击我的网页表单时，它会创建一个控件。当我点击它时，它会创建一个控件（一个盒子），我可以写手写，但是在这里写东西控制我需要再次点击因为没有焦点，我的代码的第一行创建一个控件现在我想设置一个焦点，这样当我点击它我可以直接写一些东西怎么做，因为我试过第二行

this.Sourcecode.AppendLine（\t\t\t\tdocument.getElementById（+ id +）。focus（）;）;

但似乎没有工作，而是整行写在我的网络表格顶部..

??? Anybo有一个解决方案???

推荐答案

试试这个。我已将声明放在脚本标记中。

Try this. I have placed the statement with in the script tag.

this.Sourcecode.AppendLine("<script>\t\t\t\tdocument.getElementById (" + id + ").focus();</script>");>
