Callback function for jQuery .html()?
提问by Tohid
I have the following code:
我有以下代码：
$.ajax({
type: 'GET',
url: 'index.php?route=checkout/onepagecheckout/getpaypaldata',
dataType: 'json',
success: function(json) {
$('#pp_info').html(json['output']);
$('#payment').submit();
}
});
The ajax requests receives a json object containing a html form like :
ajax 请求接收一个包含 html 表单的 json 对象，例如：
<form id="payment" method="post" action="https://www.paypal.com/cgi-bin/webscr">
<input type="hidden" value="_cart" name="cmd">
<input type="hidden" value="1" name="upload">
<input type="hidden" value="[email protected]" name="business">
<input type="hidden" value="Sample Item Name" name="item_name_1">
<input type="hidden" value="TESTI-1" name="item_number_1">
<input type="hidden" value="104.98" name="amount_1">
<input type="hidden" value="1" name="quantity_1">
<input type="hidden" value="0" name="weight_1">
<input type="hidden" value="Type" name="on0_1">
<input type="hidden" value="As Shown" name="os0_1">
<input type="hidden" value="Delivery Date" name="on1_1">
<input type="hidden" value="Jun 23,2012" name="os1_1">
<input type="hidden" value="Comments" name="on3_1">
<input type="hidden" value="test message" name="os3_1">
</form>
which contains the information that PayPal requires in order to process the order. Everything works fine except I believe sometimes the form gets submitted before the jQuery .html function is done with loading the html content.
其中包含 PayPal 处理订单所需的信息。一切正常，除了我相信有时表单会在 jQuery .html 函数完成加载 html 内容之前提交。
Is there any callback function for .html ? or any other method that I can use to solve the issue ? the PayPal data comes as a HTML form and I can't change that part, so I only have one option which is somehow load the html content and submit the form !
.html 有回调函数吗？或我可以用来解决问题的任何其他方法？PayPal 数据以 HTML 表单形式出现，我无法更改该部分，因此我只有一个选项，即以某种方式加载 html 内容并提交表单！

You may try this
你可以试试这个
success: function(json) {
$('#pp_info').html(json['output']).promise().done(function(){
$('#payment').submit();
});
}
