HTML-encoding lost when attribute read from input field

Question

I’m using JavaScript to pull a value out from a hidden field and display it in a textbox. The value in the hidden field is encoded.

For example,

Answer 1

Good answer. Note that if the value to encode is undefined or null with jQuery 1.4.2 you might get errors such as:

jQuery("

").text(value).html is not a function

OR

Uncaught TypeError: Object has no method 'html'

The solution is to modify the function to check for an actual value:

function htmlEncode(value){ 
    if (value) {
        return jQuery('
').text(value).html(); 
    } else {
        return '';
    }
}
