自动对焦当通过Ajax加载<Form> <input>时,HTML5的属性不仅适用于FireFox.为什么？

Question

下面是我通过ajax加载的表单.当我直接运行表单页面然后自动对焦c_name在Firefox中工作但是当加载ajax时它不会!虽然它与opera/safari/chrome一起工作正常!

<form action="client_entry_action.php" method="post" id="client_entry_form" name="client_entry_form">

<fieldset id="client_info_1">

    <label for="c_name">Name:</label> 
    <input type="text" name="c_name" required placeholder="Name" autofocus="autofocus" />

    <label for="c_phone">Phone Number:</label> 
    <input type="tel" name="c_phone" required placeholder="Mobile/Phone Number" />

    <label for="c_email">Email:</label> 
    <input type="email" name="c_email" required placeholder="email@example.com" />

    <label for="c_address">Address:</label> 
    <textarea name="c_address" ></textarea>


</fieldset>

<fieldset id="client_info_2">   

    <label for="c_info">Additional notes:</label> 
    <textarea name="c_info" ></textarea>

    <input type="submit" name="add_client" value="Add Client" />

</fieldset>        

</form>

Answer 1

自动对焦仅在onload触发之前完成; 它意味着一种声明性的方式来指定对初始页面加载的关注.

Answer 2

在对div调用ajax之后使用settimeout,或者使用jquery使用.ajaxComplete或.done

function theAjax(){
//after the ajax actions loaded......
//use settimeout to refocused on the input..
var t=setTimeout("focusMe()",500);

}

function focusMe(){
document.getELementById("theInput").focus();  //the new input

}

//using jquery use .ajaxComplete, or .done
 $( document ).ajaxComplete(function() {
   $("#focusOnMe").focus();
 }
