JavaScript代碼背後的硒「clickAt（）」方法？

Question

我想要做的就是硒的「clickAt（）」方法正在做什麼。它不同於selenium和普通的javascript命令「click（）」。

因爲「clickAt」正在爲正常的「點擊」 - 方法不是時的ajax測試工作。

比方說，我想做一個clickAt，在與ID的元素：身份識別碼

我怎樣才能做到這一點？

我想你正在尋找的是這樣的：

/* Fire a mouse event in a browser-compatible manner */ 

BrowserBot.prototype.triggerMouseEvent = function(element, eventType, canBubble, clientX, clientY, button) { 
    clientX = clientX ? clientX : 0; 
    clientY = clientY ? clientY : 0; 

    LOG.debug("triggerMouseEvent assumes setting screenX and screenY to 0 is ok"); 
    var screenX = 0; 
    var screenY = 0; 

    canBubble = (typeof(canBubble) == undefined) ? true : canBubble; 
    var evt; 
    if (element.fireEvent && element.ownerDocument && element.ownerDocument.createEventObject) { //IE 
     evt = createEventObject(element, this.controlKeyDown, this.altKeyDown, this.shiftKeyDown, this.metaKeyDown); 
     evt.detail = 0; 
     evt.button = button ? button : 1; // default will be the left mouse click (http://www.javascriptkit.com/jsref/event.shtml) 
     evt.relatedTarget = null; 
     if (!screenX && !screenY && !clientX && !clientY && !this.controlKeyDown && !this.altKeyDown && !this.shiftKeyDown && !this.metaKeyDown) { 
      element.fireEvent('on' + eventType); 
     } 
     else { 
      evt.screenX = screenX; 
      evt.screenY = screenY; 
      evt.clientX = clientX; 
      evt.clientY = clientY; 

      // when we go this route, window.event is never set to contain the event we have just created. 
      // ideally we could just slide it in as follows in the try-block below, but this normally 
      // doesn't work. This is why I try to avoid this code path, which is only required if we need to 
      // set attributes on the event (e.g., clientX). 
      try { 
       window.event = evt; 
      } 
      catch(e) { 
       // getting an "Object does not support this action or property" error. Save the event away 
       // for future reference. 
       // TODO: is there a way to update window.event? 

       // work around for http://jira.openqa.org/browse/SEL-280 -- make the event available somewhere: 
       selenium.browserbot.getCurrentWindow().selenium_event = evt; 
      } 
      element.fireEvent('on' + eventType, evt); 
     } 
    } 
    else { 
     evt = document.createEvent('MouseEvents'); 
     if (evt.initMouseEvent) 
     { 
      // see http://developer.mozilla.org/en/docs/DOM:event.button and 
      // http://developer.mozilla.org/en/docs/DOM:event.initMouseEvent for button ternary logic logic 
      //Safari 
      evt.initMouseEvent(eventType, canBubble, true, document.defaultView, 1, screenX, screenY, clientX, clientY, 
       this.controlKeyDown, this.altKeyDown, this.shiftKeyDown, this.metaKeyDown, button ? button : 0, null); 
     } 
     else { 
      LOG.warn("element doesn't have initMouseEvent; firing an event which should -- but doesn't -- have other mouse-event related attributes here, as well as controlKeyDown, altKeyDown, shiftKeyDown, metaKeyDown"); 
      evt.initEvent(eventType, canBubble, true); 

      evt.shiftKey = this.shiftKeyDown; 
      evt.metaKey = this.metaKeyDown; 
      evt.altKey = this.altKeyDown; 
      evt.ctrlKey = this.controlKeyDown; 
      if(button) 
      { 
       evt.button = button; 
      } 
     } 
     element.dispatchEvent(evt); 
    } 
};
