问题描述

I want to add textbox control in C# form dynamically and access its value also using javascritp

推荐答案

在您的代码后方添加这样的文本框

Add a textbox like this in your code behind

TextBox tb = new TextBox();
tb.Text = "Dynamic control";
tb.ID = "333";
form1.Controls.Add(tb);

从JavaScript函数中调用，就像这样

From JavaScript function,call like this

var txt = document.getElementById("333").value;
alert(txt);

使用document.getelementbyid


document.ge [ https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById [ ^ ]
