Applescript等待页面加载

在继续执行applescript之前,我尝试了各种解决方案来轮询elementID。我更喜欢投票,而不是有任意的延迟。

set pageNotLoaded to true
    set doForThisID to do JavaScript "document.getElementById(‘thisElementID‘);"

    repeat while pageNotLoaded is true
        try
            if (doForThisID contains "thisElementID") then
                set pageNotLoaded to false
            end if
        end try
    end repeat

我尝试过在网上提供的各种解决方案,但无济于事。任何人都可以提供任何建议来使这段代码有效吗?

你的一些逻辑是关闭的,令人困惑的事情。此外,最佳做法是让javascript通过嵌套.contains传递布尔值。这是一个脚本,它使用三种方法来测试页面是否已加载:

javascript document.readyState

javascript document.contains

一个简单的Safari调用文档文本来查找字符串。

您可以更改此脚本以仅使用其中一种。

property testingID : "login"
property testingString : "Username:"

set pageLoaded to false
tell application "Safari"
    repeat while pageLoaded is false
        set readyState to (do JavaScript "document.readyState" in document 1)
        set foundID to (do JavaScript "document.contains(document.getElementById(" & quoted form of testingID & "))" in document 1)
        set pageText to text of document 1

        if (readyState is "complete") and (foundID is true) and (pageText contains testingString) then set pageLoaded to true
        delay 0.2
    end repeat
end tell
display dialog "Ready state of page: " & readyState & return & ¬
    "ID is loaded: " & foundID & return & ¬
    "Test string is loaded: " & testingString
