Updating the Background Image Based on Text Input in JavaScript

Struggling to utilize the text entered into a text input field as a background image URL. Ensuring it is valid is key.

This snippet displays what has been attempted so far...

CSS:

body {
  margin: 0px;
  padding: 0px;
  border: 0px;
}

.bgimg {
  background-image:url('http://192.168.0.4/DesktopVersion/Inc/Images/Background/DarkWood.jpg');
}

JavaScript:

$("#SetBG").click(function() {
  var URL = document.getElementById("ImageURL").text();
  $(".bgimg").css('background-image',"url(" +URL +")");
});

HTML:

<input type="text" id="ImageURL"></input>
<button id="SetBG">Set Background</button>

A more knowledgeable individual may be able to pinpoint why this approach isn't functioning as desired.

Answer №1

When you input a value into an <input> element, it is saved as its value attribute rather than the text node inside of it (which is what jQuery's .text() function retrieves).

For example, give this a try:

$("#ChangeBG").click(function() {
    var imageURL = document.getElementById("ImageURL").value;
    $(".bg-image").css('background-image', "url(" +imageURL +")");
});
