[英]How to submit jquery ajax post request only once?
我正在使用jquery ajax post请求检查WordPress中的最终订单。
我的添加到购物车和结帐订单具有相同的代码,但结帐订单代码提交请求3次。
var j = jQuery.noConflict();
j('.wc-checkout').on('submit', function(e) {
e.preventDefault();
var billing_customer_type = j("#billing_customer_type").val();
// .. and so on...
j.ajax({
type: 'POST',
url: 'http://localhost/mywebsite/?wc-ajax=checkout',
cache: false,
data: {
'billing_customer_type': billing_customer_type,
// and so on..
},
success: function(result) {
console.log('Order Checked Out');
},
error: function(xhr, status, error) {
console.log(error);
},
complete: function() {}
});
});
<form class="wc-checkout" method="post" enctype="multipart/form-data"
novalidate="novalidate">
<div class="form-control">
<label>Lorem Ipsum: <abbr class="required" title="required">*</abbr></label>
<select name="billing_customer_type" id="billing_customer_type"
class="select thwcfd-enhanced-select select2-hidden-accessible enhanced"
data-placeholder="" tabindex="-1" aria-hidden="true">
<option value="A" selected="selected">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
</div>
<div class="form-control">
<!-- _wpnonce help protect URLs and forms from certain types of misuse -->
'.wp_nonce_field("ajax_checkout").'
<input type="submit" value="Order Now" class="epo-proceed-checkout-btn">
</div>
</form>
你知道我怎样才能让.on只提交一次? 任何想法都表示赞赏。 谢谢
检查它,但您需要在您的环境中进行测试。
var isPost = 0; $(document).ready(function() { $("button").click(function() { if (isPost == 0) { $.get("https://stackoverflow.com", function() { console.log('post'); }); isPost = 1; } }); });
<!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script> </script> </head> <body> <button>Send an HTTP GET request to a page and get the result back</button> </body> </html>
我通过添加stopImmediatePropagation();
解决了这个问题stopImmediatePropagation();
并return false;
更新的代码:
j('.wc-checkout').on('submit', function(evt) {
evt.preventDefault();
var billing_customer_type = j("#billing_customer_type").val();
// and so on...
j.ajax({
type: 'POST',
url: 'http://localhost/mywebsite/?wc-ajax=checkout',
cache: false,
data: {
'billing_customer_type':billing_customer_type,
// and so on...
},
success: function (result) {
console.log('Order Checked Out');
},
error: function(xhr,status,error) {
console.log(error);
},
complete:function(){
}
});
evt.stopImmediatePropagation(); // to prevent more than once submission
return false;
});
