问题描述

我的页面上有一个按钮.单击时应出现一个弹出框，允许用户输入文本.当按下 OK/Submit 时，我的 jscript 将使用输入的数据执行一些功能.非常简单，但我就是不知道该怎么做.

I have a button on my page. When clicked a popup box should appear allowing the user to enter text. When OK/Submit is pressed, my jscript will then perform some functions using that inputted data. Very straightforward, but I just can't figure out how to do this.

谢谢！

推荐答案

最简单的形式，你可以使用prompt(question, default):(取自 w3schools:http://www.w3schools.com/js/tryit.asp?filename=tryjs_prompt)

in it's simplest form, you could use prompt(question, default): (taken from w3schools: http://www.w3schools.com/js/tryit.asp?filename=tryjs_prompt)

function myFunction(){
    var x;
    var name=prompt("Please enter your name","Harry Potter");
    if (name!=null){
       x="Hello " + name + "! How are you today?";
      alert(x);
   }
}

其他任何东西都需要大量的 javascript &CSS 来创建带有按钮的图层并在这些按钮上单击事件

anything else would require lots of javascript & CSS to create layers with buttons and click events on those buttons
