Angular实现form自动布局

具体代码：

1.formlayoutCtrl.js

'use strict'; sxlcApp.controller('formlayoutCtrl', ['$scope', '$filter', '$http', function($scope, $filter, $http){ $scope.title = '表单布局中'; $scope.dataParamsUrl = './php/formlayout.json'; $scope.resetForm = function(num){ console.log(num) } }]);

2. formlayout.html 

<div ng-controller="formlayoutCtrl"> <span>{{title}}</span> <form w5c-form-validate="validateOptions" novalidate> <form-layout url="dataParamsUrl"> </form-layout> <button type="submit"> 提交 </button> <button type="reset" ng-click="resetForm()"> 重置 </button> </form> </div>

3. formlayout.html

<div ng-controller="formlayoutCtrl"> <span>{{title}}</span> <form w5c-form-validate="validateOptions" novalidate> <form-layout url="dataParamsUrl"> </form-layout> <button type="submit"> 提交 </button> <button type="reset" ng-click="resetForm()"> 重置 </button> </form> </div>

4. formlayoutdirective.js 

'use strict'; angular.module('form.layout', []) /** * 定义布局的服务 * @method * @param {Object} ) this.defaultTemplate [布局的模板] * @return {[type]} [description] */ .provider('formLayout', function(){ // 定义布局构造函数 function FormLayoutFn(){ /** * 定义表单元素的模板 * @type {{text: string, radio: string, checkbox: string, remember: string, range: string, time: string, date: string, datetime: string, search: string, select: string}} */ this.elementTemplate = { text : '\<div>\ <label></label>\ <input type="text" />\ </div>', password : '<div>\ <label></label>\ <input type="password" />\ </div>', radio : '\<div>\ <label></label>\ <div></div>\ </div>', email : '\<div>\ <label></label>\ <input type="email" />\ </div>', tel : '\<div>\ <label></label>\ <input type="tel" />\ </div>', url : '\<div>\ <label></label>\ <input type="url" />\ </div>', number : '\<div>\ <label></label>\ <input type="number" />\ </div>', checkbox : '<div>\ <label></label>\ <div></div>\ </div>', range : '<div>\ <label></label>\ <input type="range"/>\ </div>', time : '<div>\ <label></label>\ <input type="time"/>\ </div>', date : '<div>\ <label></label>\ <input type="date"/>\ </div>', datetime : '<div>\ <label></label>\ <input type="datetime"/>\ </div>', search : '<div>\ <label></label>\ <input type="search"/>\ </div>', select : '<div>\ <label></label>\ <select></select>\ </div>', textarea : '<div>\ <label></label>\ <textarea></textarea>\ <div>', }; //默认的模板, 可以使用如下的方式使用默认的模板 this.defaultTemplate = '<input>'; this.radioTmpl = '<label><input type="radio">radiotitle</label>'; this.checkboxTmpl = '<label><input type="checkbox">checkboxtitle</label>'; } FormLayoutFn.prototype = { /** * 获取模板 * @method getElementTemplate * @return {[type]} [description] */ getElementTemplate : function () { return this.elementTemplate; }, /** * 配置布局元素的模板 * @param configTemplate */ setElementTemplate : function(configTemplate){ this.elementTemplate = angular.extend(this.elementTemplate, configTemplate); }, /** * 实现布局函数 * @method layout * @param {[type]} eleObj 指令中的模板对象 * @param {[type]} elementObj 表单布局元素对象 * @return {[type]} [description] */ layout : function(eleObj, elementObj){ var thiz = this; var elementTemplate = this.elementTemplate; var defaultTemplate = this.defaultTemplate; var radioTmpl = this.radioTmpl; var checkboxTmpl = this.checkboxTmpl; if (angular.isObject(eleObj) && angular.isObject(elementObj)) { angular.forEach(elementObj, function(elementObjIterm, elementObjKey){ //console.log(elementObjIterm.attr.type); var type = $.trim(elementObjIterm.attr.type); var templateObj = angular.element(elementTemplate[type]); // console.log(templateObj.find('input')); switch(type){ case 'textarea' : var fileld = templateObj.find('textarea');

break; case 'radio' : var fileld = templateObj.find('#radiolist'); // var templateObj = angular.element(elementTemplate.datepicker); break; case 'checkbox' : var fileld = templateObj.find('#checkboxlist'); // var templateObj = angular.element(elementTemplate.datepicker); break; default : var fileld = templateObj.find('input') ; break; } // 设置 label 的标签名字 templateObj.find('label').html(elementObjIterm.labeltext); if ('select' == type) { var options = elementObjIterm.attr.option; angular.forEach(options, function(content, val){ var option = angular.element('<option value="'+val+'">'+content+'</option>'); fileld.append(option); }); }else if('radio' == type){ var options = elementObjIterm.attr.option; angular.forEach(options, function(content, val){ var tmpl = radioTmpl.replace('radiotitle', content); var tmplObj = angular.element(tmpl); tmplObj.find('input').attr('value', val); fileld.append(tmplObj); }); // console.log(templateObj.find('label')); }else if('checkbox' == type){ var options = elementObjIterm.attr.option; angular.forEach(options, function(content, val){ var tmpl = checkboxTmpl.replace('checkboxtitle', content); var tmplObj = angular.element(tmpl); tmplObj.find('input').attr('value', val); fileld.append(tmplObj); }); }else{ angular.forEach(elementObjIterm.attr, function(val, attrname){ fileld.attr(attrname, val); }) } eleObj.append(templateObj.append(fileld)); }); return eleObj; }else{ throw '传入的参数不是对象'; } } }; // 实例布局化构造类 var formLayout = new FormLayoutFn(); this.$get = function () { return formLayout; }; //配置布局元素的模板 this.setElementTemplate = function (configTemplate) { if (!configTemplate) return ; formLayout.setElementTemplate(configTemplate); } }); /** * 指令的实现 * @method * @return {[type]} [description] */ angular.module('form.layout') .directive('formLayout', ['$http', '$filter', 'formLayout',function($http, $filter, formLayout){ return { restrict : 'AE', scope : { url : "=", // fields : {} }, replace : true, // templateUrl : './tmpl/formlayout.html', transclude : true, // require : '?^formLayout', link : function(scope, elem, attrs){ if(!scope.url){ throw '请在指令参数url中传入获取数据的 url 的值'; } $http.get(scope.url).success(function(successData, status, headers, config){ if (!successData.code) { scope.fields = successData.data; processFormFilds(successData.data); }else{ throw '获取表单数据失败'; } }) function processFormFilds(data){ formLayout.layout(elem, data); // console.log(data); } } } }]);
