使用硒三次 [英] Triple click using selenium

问题描述

此问题类似于在此处一个>.但是，在那种情况下，海报的最终目的似乎实际上是选择一段文本，他们能够找到一种不涉及单击的变通方法.

This question is similar to the one asked here. However in that case it seems that the poster's ultimate purpose was actually to select a paragraph of text, and they were able to find a work-around which did not involve clicking.

像上面问题中的用户一样，我最初认为可以通过三次单击click方法来模拟三次单击.

Like the user in the above question I initially thought that it would be possible to simulate a triple-click by calling the click method three times.

new Actions(driver)
  .moveToElement(svgElement, posX, posY)                     
  .click()
  .click()
  .click()
  .perform()

但是，这不起作用，因为我的JavaScript代码检查了 UIEvent 实例的 detail 属性，并且始终为 1 每次调用 click .因此，以下代码段:

However, this doesn't work as the my javascript code checks the the detail attribute of the UIEvent instance, and this is always 1 for each call to click. Thus the following snippet:

function clickHandler (event) {
    if (event.detail == 1) {
        singleClickHandler() 
    }
    if (event.detail == 2) {
        doubleClickHandler() 
    }
    if (event.detail == 3) {
        tripleClickHandler() 
    }

导致通过Selenium调用 singleClickHandler 三次，而 singleClickHandler ， doubleClickHandler 和 tripleClickHandler 时就会被调用.

causes singleClickHandler to be called three times when called via Selenium, whereas each of singleClickHandler, doubleClickHandler, and tripleClickHandler is called once when this is exercised manually via the browser (Firefox).

如何通过硒触发 detail 等于3的点击事件?

How do I cause a click event with detail equal to 3 to be triggered via selenium?

推荐答案

当前api没有提供一种模拟三次点击的方法，该方法会发出带有点击计数的一次点击事件.因此，您最好的机会可能是使用executeScript模拟事件:

The current api doesn't provide a way to simulate a triple click which would emit a single click event with the count of clicks. So your best chance is likely to simulate the event with executeScript:

String JS_CLICK_TRIPLE = 
  "var target = arguments[0];                                 " +
  "var offsetX = arguments[1];                                " +
  "var offsetY = arguments[2];                                " + 
  "var rect = target.getBoundingClientRect();                 " +
  "var cx = rect.left + (offsetX || (rect.width / 2));        " +        
  "var cy = rect.top + (offsetY || (rect.height / 2));        " +
  "                                                           " +
  "emit('mousedown', {clientX: cx, clientY: cy, buttons: 1}); " +
  "emit('mouseup',   {clientX: cx, clientY: cy});             " +
  "emit('mousedown', {clientX: cx, clientY: cy, buttons: 1}); " +
  "emit('mouseup',   {clientX: cx, clientY: cy});             " +
  "emit('mousedown', {clientX: cx, clientY: cy, buttons: 1}); " +
  "emit('mouseup',   {clientX: cx, clientY: cy});             " +
  "emit('click',     {clientX: cx, clientY: cy, detail: 3});  " +
  "                                                           " +
  "function emit(name, init) {                                " +
    "target.dispatchEvent(new MouseEvent(name, init));        " +
  "}                                                          " ;


Actions action1 = new Actions(driver);
action1.moveToElement(yourElement, posX, posY).perform();

((JavascriptExecutor)driver).executeScript(
    JS_CLICK_TRIPLE, yourElement, posX, posY);
