How do I execute my function whenever the input field loses its focus?-CodePudding

In Javascript, I want to execute my function whenever the textbox loses its focus. What's the easiest way to do this?

CodePudding user response：

So you have two options

OnFocousOut

<input type="text" 
           name="input" 
           value="Lorem"
           onfocusout="yourFunction();" />

or OnBlur

 <input type="text" onblur="myFunction()">

CodePudding user response：

In most of the case I don't use onblur I use onchange method because it will indicate user only if user change the value of text box so i think it's user friendly.

Easiest method is to add your javascript in html tag

   <input type = "text" onchange = "yourFunction()">

but this is not a good practice. Write your javascript in external file.
