如何在js文件中调用函数？

Question

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.

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):

我怎样才能做到这一点？

$.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) {

});

由于丹的答案的解决方案是非常接近,但事件不会工作,因为e.preventDefault();被调用.

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>');
		});
	};
	
	// =========================================================================

	p._initValidation = function () {
		if (!$.isFunction($.fn.validate)) {
			return;
		}
		$.validator.setDefaults({
			highlight: function (element) {
				$(element).closest('.form-group').addClass('has-error');
			},
			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);
		});
	};
	
	// =========================================================================

	window.materialadmin.AppForm = new AppForm;

更新1 我window.materialadmin.AppForm.Initilize在ajax响应中添加但事件不起作用

更新2 这里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 () {

            });
        }
    });

Answer 1

您可以将代码包装在全局函数中.

(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,则执行它.

.success(function (data) {
  $("#products-list").html(data);
  //**PERFORM INIT OF JS FILE**
  window.main();
}).error(function (data) {

});

编辑:看起来你正在全局对象上公开initialize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) {

});

Answer 2

与更新 2 相关

尝试通过委托注册您的活动：

$(document).on(
    'click',
    '.ProductOnlyForDemonstation button, .IncludeInMainPage button, .Active button',
    function() {
        // Your code
    }
);

我想您正在加载某些内容并在响应后呈现新的页面内容，因此以前注册的事件不会附加到新元素。通过委派，即​​使在元素动态添加到 DOM 后（如果它们与委派选择器匹配），您也可以让事件正常工作，因为事件会附加到按钮document并从按钮冒泡。您可以将事件附加到 DOM 中比事件document本身更深的位置，但附加到包含动态内容的元素（换句话说：附加到完成请求后不会被覆盖的最接近的元素）。

附言。您还可以向所有类添加一些独特的类.ProductOnlyForDemonstation button, .IncludeInMainPage button, .Active button并将事件委托给该类（更短的定义）
