如何使用CasperJS移动jquery-ui滑块

问题描述

有什么方法可以将 jQuery UI – Slider 与 CasperJS 吗?

Is there any way to move the jQuery UI – Slider with CasperJS ?

我还发现了这个 github问题，同时寻找了一种可能性，只需点击向左或向右滑动滑块以移动手柄.但这对我也不起作用.

I also found this github issue while searching for a possibility to just click on the left or right of the slider to move the handle. But this doesn't worked for me as well.

有什么主意吗?

推荐答案

这是完整的演示:

// test_slider.js

var casper = require('casper').create(),
    mouse = require('mouse').create(casper),
    utils = require('utils');

casper.start('http://jqueryui.com/resources/demos/slider/default.html')
      .then(function() {
        var slider = this.getElementBounds('.ui-slider');
        var handle = this.getElementBounds('.ui-slider-handle');

        this.echo('=== BEFORE ===', 'INFO');
        this.echo(this.getElementAttribute('.ui-slider-handle', 'style'));
        this.capture('before.png');

        this.echo('=== DRAGGING ===', 'INFO');
        this.mouse.down('.ui-slider-handle');
        this.mouse.move(slider.left + slider.width / 2, slider.top + slider.height / 2);
        this.mouse.up('.ui-slider-handle');

        this.echo('=== AFTER ===', 'INFO');
        this.echo(this.getElementAttribute('.ui-slider-handle', 'style'));
        this.capture('after.png');
      })
      .run();

结果

$ casperjs test_slider.js
=== BEFORE ===
left: 0%;
=== DRAGGING ===
=== AFTER ===
left: 50%;
