I got this line in html :
<input type="text" name="number" value= "" style="width: 20px;border:#FFFFFF none 0px;" readonly></p>
And I also have a variable in a function in javascript that I would like to put in the value of the html line.
http://jsfiddle.net/6v28hj75/1/
function myFunction() {
input = document.getElementsByTagName('input')[0];
input.value = "Your value here";
}
myFunction()
I made you a simple example, pure Javascript.
For this purpose you can use jQuery like this :
jQuery(function($){ var foo = 'bar'; $('input[name="number"]').val(foo); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" name="number" value="">
You can access JavaScript variables in JSP as below:
JavaScript:
var fruit = "Apple";
$("#someTextBox").val(fruit);
JSP:
<input type="text" id ="someTextBox" name="number" style="width: 20px;border:#FFFFFF none 0px;"></p>
