Question

我尝试了下面的代码，但没有奏效。我正在使用Angular4。如果句柄点击的输入不小于3，我想触发点击事件。

import { Component, OnInit, ElementRef } from '@angular/core';

@Component({
    selector: 'box-frame',
    template: `
            <div>
              <div (click)="handleClick(i)" id="box{{i}}" *ngFor="let i of array"></div>   
            </div>
          `
})
export class BoxFrameComponent implements OnInit {
    array: any = [1, 2, 3, 4, 5, 6];
    constructor(private eleRef: ElementRef) { };
    ngOnInIt() {
    };
    handleClick(n: number) {
        if (n < 3) {
            console.log(n);
        } else {
            let smallBox = this.eleRef.nativeElement.querySelector('#box' + n - 1);
            //this didn't work
            smallBox.dispatchEvent('click');
        }

    };
};

from P4 import P4
import logging

FORMAT = '%(asctime)-15s: %(name)s: %(levelname)s :  %(message)s'
logging.basicConfig(format=FORMAT, filename='/var/log/pytest.log', level=logging.INFO)

def reader():
    p4 = P4()
    p4.port = "ssl:perforce1.cec.lab.emc.com:1666"
    p4.user = "perforce"
    p4.charset = 'utf8'
    p4.password = "Password"
    p4.connect()
    p4.run_trust("-i", '80:25:3E:E0:A6:58:8E:13:4F:9E:8C:C8:BF:C3:26:C2:91:2F:78:33')
    p4.run_login()

    result = p4.run('license', '-u')
    logging.info ("User limit is :" + result[0].get('userLimit'))

    #
    p4.disconnect()
