问题
I'm creating my page using Javascript. It is a login page and I need to use autofocus on username input text. This operation works on IE and Chrome, but doesn't on Mozilla! This is the HTML I have been adding using JS:
'<input id="username" class="loginInput" data-bind="value: userName, valueUpdate: \'afterkeydown\'" type="text" name="User" autofocus><!--User Input text end /-->'
When i load the page with Mozilla this input is set this way:
<input id="username" class="loginInput" type="text" autofocus="" name="User" data-bind="value: userName, valueUpdate: 'afterkeydown'">
I really can't understand why "autofocus" attribute is set in that way. I even tried by adding the attribute using JQuery $("#username").attr('autofocus','autofocus') and works only on Chrome and IE.
The secondo problem comes when i go to the login page from another page and autofocus issue comes with every browser.
Can you help me?
回答1:
You can try with:
$("#username").focus();
after the page has been loaded.
回答2:
Instead of using the autofocus attribute, try:
$("#username").focus();
