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.

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
