阿贾克斯多次提交

Question

>我在php中创建了一个应用程序，我正在使用引导模型使用AJAX更新用户详细信息。现在有两种形式：首先更新用户的详细信息并向其他用户添加注释。当我尝试向 AJAX 提交表单并尝试提交表单时，它不起作用，当我使用 ajaxComplete 函数时，我的表单数据已成功提交，但此时它同时多次提交表单。

$(document).ajaxComplete(function() {
$("#add-remarks").on('submit', (function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: $("#add-remarks").attr("action"),
cache: false,
context: this,
data: $("#add-remarks").serialize(), //only input
success: function(data) {
var obj = JSON.parse(data);
$("#add-remarks")[0].reset();
if (obj['msg'] == 'isuccess') {
notification('insert');
} else {
notification('error');
}
}
});
}));

<div class="modal-body">
<div class="row">
<div class="col-md-12">
<div class="card-group-control card-group-control-right" id="accordion-model">
<div class="card">
<form method="post" name="update-user-details" id="update-user-details" action="">
<div class="row">
<div class="col-md-4">
<div class="form-group form-group-float">
<label class="d-block font-weight-semibold">First Name</label>
<input type="text" class="form-control" placeholder="First Name" name="customer_name" id="customer_name">
</div>
</div>
<div class="col-md-4">
<div class="form-group form-group-float">
<label class="d-block font-weight-semibold">Mobile</label>
<input type="text" class="form-control" placeholder="Mobile" name="mobile_number" id="mobile_number">
</div>
</div>
<button type="submit" class="btn bg-blue">Save Changes</button>
</div>
</form>
<form method="post" name="remarks" id="remarks" action="">
<div class="row">
<div class="col-md-4">
<div class="form-group form-group-float">
<label class="d-block font-weight-semibold">Remarks</label>
<input type="text" class="form-control" placeholder="Remarks" name="remarks" id="remarks">
</div>
</div>
<button type="submit" class="btn bg-blue">Save Changes</button>
</div>
</form>
</div>
</div>
</div>
</div>
</div>

将这段代码移到 ajaxComplete(( 函数之外。您可能以某种方式多次触发 ajaxComplete 函数，导致表单提交有多个事件侦听器。

$("#add-remarks").on('submit', (function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: $("#add-remarks").attr("action"),
cache: false,
context: this,
data: $("#add-remarks").serialize(), //only input
success: function(data) {
var obj = JSON.parse(data);
$("#add-remarks")[0].reset();
if (obj['msg'] == 'isuccess') {
notification('insert');
} else {
notification('error');
}
}
});
}));
