AppleScript“缺失值"中的Javascript(用于Safari中的单击按钮) [英] Javascript within AppleScript 'missing value' (for clicking button in Safari)

问题描述

我有以下包含Javascript的AppleScript:

I have the following AppleScript with Javascript contained:

set buttontext to "Add Option"
set buttonloc to 1

tell application "Safari"
    activate
    tell window 1
        do JavaScript "var buttonTags = document.getElementsByTagName(\"button\"); 
        var searchText = \"" & buttontext & "\"; 
        var found; 
        for (var i = 0; i < buttonTags.length; i++) 
        {if (buttonTags[i].textContent == searchText) {
        found = buttonTags[i]; break;
        }
        }
        buttonTags[" & buttonloc & "].click();"
    end tell
end tell

它可以正常编译，但是在执行时没有任何动作，并且我收到缺少值"错误.它旨在在Safari中浏览网页，并允许用户指定按钮文本和等级以便能够单击它.

It compiles fine but upon execution there is no action and I receive a 'missing value' error. It is designed to traverse a web page in Safari and allow a user to specify the button text and rank to be able to click it.

直接在Safari的开发控制台中执行此Javascript时，它可以工作，但是我需要在AppleScript中将其包装到更长的例程中.

When execute this Javascript directly in Safari's dev console it works, but I need to have it in AppleScript to wrap it into a longer routine.

建议感激！

推荐答案

我设法通过将JS的末尾修改为:

I have managed to solve this with amending the end of the JS to:

buttonTags[" & buttonloc & "].click();" in current tab
