How To Get Input Via A Popup And Place Text In A Variable Via Javascript/jquery

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 t

Solution 1:

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);
   }
}

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

Solution 2:

Paste this code inside your head tags between script tags

HTML

<button id="button">Get Text</button>​

JS

window.onload=function()
{
    var el=document.getElementById('button');
    el.onclick=function(){
        var my_text=prompt('Enter text here');
        if(my_text) alert(my_text); // for example I've made an alert
    }
}
