Bootstrap Change button loading state _javascript Tips

When there is an activation button inside the bootstrap, the button becomes unusable;

According to the method introduced in the official website is to add a data-loading-text= "Loading ..." in button buttons. Properties, and then the JS overall code is like this:

Copy Code code as follows:

<button type= "button" id= "MyButton" data-loading-text= loading ... "class=" btn btn-primary "autocomplete=" Off ">
Loading State
</button>

<script>
$ (' #myButton '). On (' click ', function () {
var $btn = $ (this). Button (' Loading ')
Business logic ...
$btn. button (' Reset ')
})
</script>

Where the autocomplete= "off" property is for the FF browser after the page is loaded, the disabled state is not automatically released.
When I use the above code directly, I find that the loading state is not.
Then I changed it myself, and I wrote it, and it was OK.

Copy Code code as follows:

<script>
For smiling words Landing button and reviewing button to change button loading status
function Loag () {
var btn = $ ("#btn_login");
Btn.button (' loading ');
settimeout (function () {Btn.button (' reset ');},2000);
}
</script>
<button type= "button" class= "btn btn-default" data-loading-text= loading ... "autocomplete=" Off "onclick=" Loag () " Id= "Btn_login" > Login </button>
