jQuery remove text from input

Question

Is there a possible way in jQuery to remove a specified value from an input? Like this:

Example:

The button:

<button>Click to remove page 4</button>

After:

<input type="text" name="test[]" value="Page1, Page2, Page3, Page5"> 

Answer 1

You can do:

HTML

<input type="text" id="someput" name="test[]" value="Page1, Page2, Page3, Page4, Page5">

JS

var new_val = $("#someput").val();
new_val = new_val.replace("what to replace", "");
$("#someput").val(new_val);
