我试图操纵我在互联网上找到的这段代码。这对我单击链接很有用。但是在某些情况下，我需要使用右键单击功能打开该元素的contextMenu。
如果有一种方法可以将其转换为打开contextMenu，请参见此代码。
我试图用一些代码来操纵它，但是没有成功。
(function run (pXPathStr) {
'use strict';
var ptyScriptName = "Click on Link Identified by XPath"
/*
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PURPOSE: Click on the Hyperlink Identified by the XPath provided by KM
RETURNS: One of these, as text:
• "OK" -- if successful, no errors
• "[ERROR]" at start of results if a script error occurred.
KM VARIABALES REQUIRED:
• xPath -- the full XPath to the Link
EXAMPLE XPATH:
//*[@id="ctl00_MainContent_ucEStatements_dlStatements_ctl00_lbStatementDate"]
KM VARIABLES SET:
• NONE
REF:
• [Introduction to using XPath in JavaScript](https://developer.mozilla.org/en-US/docs/Introduction_to_using_XPath_in_JavaScript)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*/
//--- GET THE XPATH FROM KM ---
var xPathStr = document.kmvar.xPath;
var returnResults = "TBD";
//--- GET THE HTML ELEMENT IDENTIFIED BY THE XPATH ---
var elemFound = document.evaluate(
xPathStr, document, null, 0, null
).iterateNext();
if (elemFound) {
//--- CLICK ON THE LINK ---
elemFound.click();
returnResults = "";
}
else {
//--- ERROR: ELEMENT WAS NOT FOUND ---
returnResults = '[ERROR] Element NOT FOUND for XPath:\n' + xPathStr;
alert(returnResults);
}
return returnResults;
})();
/*
*/
我希望运行此功能会打开元素的contextMenu。
我将在图像元素上使用contextMenu下载到我的桌面上。
这是在链接中单击鼠标右键后要打开的菜单的图像。 The is the action result in the image link I want to happen
