摘要：
[]：roleIds.substring。拆分（'，'）；提交时，使用逗号链接roles=this。角色ID。加入（“，”）；this.editmarketSource[“roleId”]=角色。长度˃0？
更改过程让数据不时时更新
let add = JSON.stringify(editMarketChannel);
this.editMarketChannel = JSON.parse(add);
这个为函数传入的对象，Obj
提示信息
成功的
this.msgs = [];
this.msgs.push({severity:'success', summary:'提示信息', detail:'修改成功'});
const timers = setInterval(() => {
this.clear();
clearInterval(timers);
}, 3000);
失败的
this.msgs = [];
this.msgs.push({severity: 'error', summary: '错误信息', detail: '渠道不能为空'});
const timers = setInterval(() => {
this.clear();
clearInterval(timers);
}, 3000);
clear() {
this.msgs = [];
}msgs: Message[] = [];
引入这个组件
import {Message} from 'primeng/primeng';ngOnInit() {项目初始化
就比如vue的生命周期 钩子函数mouted(){}
}三元运算符转换格式
let roleIds = this.roleId.length<=0? '': ','+this.roleId.join(",")+',';
this.addMarketSource["roleId"] = roleIds;前后都加逗号
切割字符串前面和后面的逗号 然后中间用逗号切割
const roleIds = editmarketSource.roleId;
this.roleId = roleIds === null? []: roleIds.substring(1, roleIds.length-1).split(',');
提交的时候用逗号链接起来
let roles = this.roleId.join(",");
this.editmarketSource["roleId"] = roles.length>0? ','+ roles+',': '';下拉框增加显示全部内容选项
let marketList=[];
marketList.push({marketSourceId:'',marketSource:'全部'});
data.forEach(function(element) {
marketList.push(element);
});
this.marketSourceList = marketList;
angular切换分页
this.totalRecords = data.data.total;(请求数据时)
组件
<p-paginator rows="10" totalRecords="{{totalRecords}}" (onPageChange)="paginate($event)"></p-paginator>方法
paginate($event) {
this.leadList.page = $event.page + 1;
this.loadData();

Ui框架里面的样式更改

data.forEach(function(element) {

});根据日期获取星期几
if(date.getDay()==0){

});1、 JSON.parse()用于从一个字符串中解析出json对象。
2、 JSON.stringify()用于从一个对象解析出字符串。
3、 data = data === undefined ? [] : data;

selector: 'app-member',
templateUrl: './member.component.html',
styleUrls: ['./member.component.css'],
providers:[HttpService,DatePipe,CommonService]
})constructor(
private datePipe: DatePipe,
public commonService:CommonService,这部分可以不写
public httpService: HttpService这部分可以不写
