I'm wanting to take whatever is entered into input and when the button is clicked, it removes everything after the first two characters that were entered.
For example if I entered in "BT2J43" I would like it to cut it down to "BT" in the input field is the possible?
Here's my fiddle below, I'm just learn jquery, go easy on me!
https://jsfiddle.net/ktd9gbu9/1/
$("#submit123").click(function() {
$("#text123").text($("#text123")[0].innerText.substr(2));
});
<input type="search" name="table_filter" id="text123" required>
<input name="submit" type="Submit" id="submit123" value="Search">
Answer 1
You want to use .val() instead of .text():
$("#submit123").click(function () {
$("#text123").val($("#text123").val().substr(0, 2));
});

Also with substr() you forgot the starting index.
Answer 2
You can do that easily but you need to target .val()
Here is a clean code that may help you! :)
$("#button").click(function () {
var search = $("#search");
search.val(search.val().substr(0, 2));
});
