Get the value in an input text box

Question

What are the ways to get and render an input value using jQuery?

Here is one:

Answer 1

You have to use various ways to get current value of an input element.

METHOD - 1

If you want to use a simple .val(), try this:

Get values from Input

// use to select with DOM element.
$("input").val();

// use the id to select the element.
$("#txt_name").val();

// use type="text" with input to select the element
$("input:text").val();

Set value to Input

// use to add "text content" to the DOM element.
$("input").val("text content");

// use the id to add "text content" to the element.
$("#txt_name").val("text content");

// use type="text" with input to add "text content" to the element
$("input:text").val("text content");

METHOD - 2

Use .attr() to get the content.

I just add one attribute to the input field. value="" attribute is the one who carry the text content that we entered in input field.

$("input").attr("value");

METHOD - 3

you can use this one directly on your input element.

$("input").keyup(function(){
    alert(this.value);
});
