ng-checked选择和点击增加dom
1.需求
在添加页面实现一个checkbox的选择,然后在详情页面展示时,会自动选上之前被选中的。
2.添加页面
看官最好将这个代码复制过去看看效果。
<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body><div ng-app="myApp" ng-controller="myCtrl" >
选择
<div ng-repeat="item in list">
<input type="checkbox" name="tagName" value="http://www.mamicode.com/item.id" ng-click="select(item.id,$event)"> {{item.shortName}}
</div>
结果:{{result}}</div><script>
var app = angular.module(‘myApp‘, []);
app.controller(‘myCtrl‘, function($scope) {
//创建checkbox用的
$scope.list=[{"id":1,"shortName":"张三"},{"id":2,"shortName":"李四"},{"id":3,"shortName":"王二"}];
//存储已选
$scope.result = [];
//触发事件
$scope.select = function(id,event){
console.log(event)//打印看看这是什么,有利于理解
console.log(action)
var action = event.target;
if(action.checked){//选中,就添加
if($scope.result.indexOf(id) == -1){//不存在就添加
$scope.result.push(id);
}
}else{//去除就删除result里
var idx = $scope.result.indexOf(id);
if( idx != -1){//不存在就添加
$scope.result.splice(idx,1);
}
}
};
});
</script></body></html>
3.详情展示
//假设添加页面的结果是:$scope.result = [3,2];
<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body>
<div ng-app="myApp" ng-controller="myCtrl" >
回写时设置不可选,即设ng-disabled="true"
<div ng-repeat="item in list">
<input type="checkbox" name="tagName" ng-checked="isSelected(item.id)" value="http://www.mamicode.com/item.id" ng-disabled="true" > {{item.shortName}}
</div>
结果:{{result}}</div>
<script>
var app = angular.module(‘myApp‘, []);
app.controller(‘myCtrl‘, function($scope) {
//创建checkbox用的
$scope.list=[{"id":1,"shortName":"张三"},{"id":2,"shortName":"李四"},{"id":3,"shortName":"王二"}];
//在添加页面得到的结果
//你会发现,顺序也不会影响结果
$scope.result = [3,2];
//被选中条件:ng-checked的结果为true
$scope.isSelected = function(id){
return $scope.result.indexOf(id)!=-1;
//只要返回的结果为true,则对应的checkbox就会被选中,
//所以我的思路是看存添加页面的结果里是否含有当前id即value值,
//有就返回的true,没有就返回false
};
});
</script></body></html>
{"list":[{"content":"普通发票","type":1},{"content":"电子产品","type":2}]} 要传给后台的数据 页面展示 上面传type=1,下面增加的填type=2
html
div.form-group
label.control-label.col-md-3 发票类型
div.col-md-6
label.checkbox.pull-left(ng-repeat="(key,type) in globalConfig.invoice_type" style="margin-left:30px")
input(type="checkbox" name="invoice_type" ng-model="invoice_type[key]" ng-true-value="http://www.mamicode.com/true" ng-false-value="" ng-click="")
| {{type}}
//- select.form-control(ng-options="key as value for (key,value) in globalConfig.invoice_type" ng-model="info.list.invoice_type" multiple="true")
//- option(value=http://www.mamicode.com/‘‘) (发票类型可多选)
div.form-group
label.control-label.col-md-3 发票内容
div.col-md-6
.form-group
span.btn.btn-danger(ng-click="addFn(sendData.list)") 添加
div(ng-repeat="spec in sendData.list")
.input-group
input.form-control(type="text" ng-model="spec.content" name="brand_name" )
.input-group-addon(ng-click="removeFn( sendData.content,spec)")
i.glyphicon.glyphicon-remove
js
angular.module(‘laoyou‘)
.controller(‘invoiceCtrl‘, [‘$scope‘,‘$http‘,‘$stateParams‘,‘api‘,function($scope, $http, $stateParams,api){
$scope.sendData = http://www.mamicode.com/{list:[]};
$scope.addFn=function(list,item){
// console.log(list)
// [{type: 2, content: "ert"}, {type: 2, content: "fgh"}]
list.push({type:2});
/*if(list == undefined){
list = [];
}else{
list.push({});
}*/
}
$scope.removeFn=function(list,item){
var index=list.indexOf(item);
list.splice(index,1)
}
// 初始化invoice_type
$scope.invoice_type={};
$scope.sendFn = function () {
sendData=http://www.mamicode.com/angular.copy($scope.sendData);
// sendData= http://www.mamicode.com/{};
// sendData.content = $scope.sendData.content;
var type= [{"content":"普通发票","type":1},{"content":"增值税专用发票","type":1},{"content":"电子发票","type":1}];
// sendData.type=[];
var invoice=$scope.invoice_type;
console.log(invoice)
for(var x in invoice){
if(invoice[x]){
sendData.list.push(type[x-1]); //传入想要的数
}
}
console.log(sendData);
/*var info = {};
info.list = [sendData];*/
// console.log(info);
$http.post("invoice/save", sendData).success(function (data) {
if (data.statusCode === ‘0‘) {
alert("提交成功");
/*if ($scope.pageModel === ‘add‘) {
$state.go("home.employee.view", {
id: data.data

}else{
