Here is my code looks like, I would like to be able to use whatever user inputs as the value for my showColor function. I used document.getElementsByName, but I got some errors Type error. Can somebody help? Thanks!
<input type="text" name="color" value="Input Your Fav Color">
<button type="button" onClick="showColor('red')">Show Color</button>
I'm guessing it's because you're doing this
document.getElementsByName('color').value
You should be doing this instead
document.getElementsByName('test')[0].value
Because getElementsByName returns a collection, or alternatively give the element an id and use getElementById instead.
You will want to assign an id to the target input so that you can easily retrieve its value via javascript.
<input id="userColor" type="text" name="color" value="Input Your Fav Color" >
You can then retrieve the value like so:
var usercolor = document.getElementById('userColor').value;
Or using your example
<button type="button" onClick="showColor(document.getElementById('userColor').value)">Show Color</button>
Use DOM:
<button type="button" onClick="showColor(document.getElementsByName('color')[0].value)">Show Color</button>
There will be problem if you have more elements with name color on the page, but I assume you haven't.
You actually need to be using .getElementById("color") and have the input be
<input type="text" name="color" id="color" value="Input Your Fav Color">
