Updating input value attribute with jQuery

Question

I currently calculate a random value with jQuery and save it to a variable.

I want this variable to be the value of:

<input type="text" class="mastery_num" name="mastery_num" id="mastery_num" value="VALUE_FROM_JQUERY"></input>

How can I do this?

You're looking for val:

var your_variable = doMyCalculation();
$("#mastery_num").val(your_variable);

$("#mastery_num").val(your_saved_variable);

.val() is jQuery's equivalent of the plain JavaScript .value property. .val() either returns or sets the value depending on whether you supply a value to it.

Plain JavaScript version, for future viewers:

document.getElementById("mastery_num").value = your_saved_variable;
