我有一个 JavaScript 文件 AppForm.js，我希望在成功的 ajax post 响应后重新初始化它。
文件本身包含，等等
(function(namespace, $) {
"use strict";
var AppForm = function() {
// Create reference to this instance
var o = this;
// Initialize app when document is ready
$(document).ready(function() {
o.initialize();
});
};
var p = AppForm.prototype;
p.initialize = function() {
// Init events
this._enableEvents();
this._initRadioAndCheckbox();
this._initFloatingLabels();
this._initValidation();
};
p._enableEvents = function () {
//blah blah blah
e.preventDefault();
};
p._initRadioAndCheckbox = function () {
};
p._initFloatingLabels = function () {
};
p._initValidation = function () {
};
window.materialadmin.AppForm = new AppForm;
}(this.materialadmin, jQuery)); // pass in (namespace, jQuery):
我该怎么做？
$.ajax({
url: path, type: "POST", cache: "false",
dataType: "html",
contentType: "application/json; charset=utf-8",
traditional: true,
data: JSON.stringify(postData)
}).success(function (data) {
$("#products-list").html(data);
//**PERFORM INIT OF JS FILE**
}).error(function (data) {
});
感谢 Dan 的回答，解决方案非常接近，但是事件无法正常工作 因为调用了 e.preventDefault();。
这是完整的脚本
(function(namespace, $) {
"use strict";
var AppForm = function() {
// Create reference to this instance
var o = this;
// Initialize app when document is ready
$(document).ready(function() {
o.initialize();
});
};
var p = AppForm.prototype;
// =========================================================================
// INIT
// =========================================================================
p.initialize = function() {
// Init events
this._enableEvents();
this._initRadioAndCheckbox();
this._initFloatingLabels();
this._initValidation();
};
// =========================================================================
// EVENTS
// =========================================================================
// events
p._enableEvents = function () {
var o = this;
// Link submit function
$('[data-submit="form"]').on('click', function (e) {
e.preventDefault();
var formId = $(e.currentTarget).attr('href');
$(formId).submit();
});
// Init textarea autosize
$('textarea.autosize').on('focus', function () {
$(this).autosize({append: ''});
});
};
// =========================================================================
// RADIO AND CHECKBOX LISTENERS
// =========================================================================
p._initRadioAndCheckbox = function () {
// Add a span class the styled checkboxes and radio buttons for correct styling
$('.checkbox-styled input, .radio-styled input').each(function () {
if ($(this).next('span').length === 0) {
$(this).after('<span></span>');
}
});
};
// =========================================================================
// FLOATING LABELS
// =========================================================================
p._initFloatingLabels = function () {
var o = this;
$('.floating-label .form-control').on('keyup change', function (e) {
var input = $(e.currentTarget);
if ($.trim(input.val()) !== '') {
input.addClass('dirty').removeClass('static');
} else {
input.removeClass('dirty').removeClass('static');
}
});
$('.floating-label .form-control').each(function () {
var input = $(this);
if ($.trim(input.val()) !== '') {
input.addClass('static').addClass('dirty');
}
});
$('.form-horizontal .form-control').each(function () {
$(this).after('<div class="form-control-line"></div>');
});
};
// =========================================================================
// VALIDATION
// =========================================================================
p._initValidation = function () {
if (!$.isFunction($.fn.validate)) {
return;
}
$.validator.setDefaults({

},
unhighlight: function (element) {
$(element).closest('.form-group').removeClass('has-error');
},
errorElement: 'span',
errorClass: 'help-block',
errorPlacement: function (error, element) {
if (element.parent('.input-group').length) {
error.insertAfter(element.parent());
}
else if (element.parent('label').length) {
error.insertAfter(element.parent());
}
else {
error.insertAfter(element);
}
}
});
$('.form-validate').each(function () {
var validator = $(this).validate();
$(this).data('validator', validator);
});
};
// =========================================================================
// DEFINE NAMESPACE
// =========================================================================
window.materialadmin.AppForm = new AppForm;
}(this.materialadmin, jQuery)); // pass in (namespace, jQuery):更新 1
我在 ajax 响应中添加了 window.materialadmin.AppForm.Initilize 但事件不起作用
更新 2 这是回发后不起作用的代码。
$(".ProductOnlyForDemonstation, .IncludeInMainPage, .Active")
.on('click', 'button', function(){
$('.sweet-overlay').toggle();
if (jQuery("#FORM").valid()) {
var id = $(this).attr("data-id");
$.post("/product/DemoIncludeActive", {
"Id": id,
"ProductOnlyForDemonstation": $("#ProductOnlyForDemonstation-" + id).is(':checked'),
"IncludeInMainPage": $("#IncludeInMainPage-" + id).is(':checked'),
"Active": $("#Active-" + id).is(':checked'),
},
function (data) {
}).success(function (data) {
}).error(function () {
});
}
});
最佳答案
您可以将您的代码包装在一个全局函数中。
(function(namespace, $) {
"use strict";
window.main = function() {
var AppForm = function () {
// ...
};
};
window.main(); // you can initialize it here
)(this.materialadmin, jQuery);
如果响应成功则执行。
.success(function (data) {
$("#products-list").html(data);
//**PERFORM INIT OF JS FILE**
window.main();
}).error(function (data) {
});
编辑:看起来您是在全局对象上公开初始化方法。您可以在 AJAX 响应完成时调用该 init 方法。
.success(function (data) {
$("#products-list").html(data);
//**PERFORM INIT OF JS FILE**
window.materialadmin.AppForm.initialize();
}).error(function (data) {
});
