I'm new to JavaScript and have run into a challenge (for me). I've looked online for a solution, but to my surprise I couldn't find it. This must have a very basic solution!

The problem: I want JavaScript to execute an if statement based on user input from a text field.

<input id="text_a" type="text;" />
<p id="answer"></p>
<button onclick="myFunction()">Check</button>

<script>
function myFunction()
{
var a=document.getElementById("text_a").vlaue;

if (a=="hello")
  {
document.getElementById("answer").innerHTML="Correct!";
  }
else
  {
document.getElementById("answer").innerHTML="Oops!";
  }
}
</script>

When I try this creation out, no matter what is entered into the text input (even the right answer) the else statement is executed. What am I missing to get the if statement to execute?? Thanks in advance for any and all help

• javascript

• You misspelled "value", try a=document.getElementById("text_a").value; – faino Commented Mar 23, 2013 at 20:45

• This question appears to be off-topic because it is just a typo. – Kuba hasn't forgotten Monica Commented Sep 14, 2013 at 18:25

First Remove ';' from type attribute

<input id="text_a" type="text" />

and you have spell mistake in value

var a=document.getElementById("text_a").value;

Here is working Example.

You've spelt value wrong:

var a=document.getElementById("text_a").vlaue;

Should be

var a=document.getElementById("text_a").value;

You misspelled value.

var a=document.getElementById("text_a").vlaue;
