Question

我在safari中从一行中提取了一些数字。

这是脚本的一小部分示例

set DATA39 to "0"
set DATA40 to "0"

to getInputByClass2(theClass, num) -- defines a function with two inputs, theClass and num
    tell application "Safari" --tells AS that we are going to use Safari
        set input to do JavaScript "
document.getElementsByClassName('" & theClass & "')[" & num & "].innerHTML;" in document 1 -- uses JavaScript to set the variable input to the information we want
    end tell
    return input --tells the function to return the value of the variable input
end getInputByClass2



getInputByClass2("sortable DATAId", 1)
set theText to Unicode text
set DATA1 to getInputByClass2("sortable DATAId", 1)
###################################################################
getInputByClass2("sortable DATAId", 2)
set theText to Unicode text
set DATA to getInputByClass2("sortable DATA", 2)
###################################################################

我不知道我收集了多少数据，所以现在，我将脚本限制为前30个结果

（data1，data2 data3）

唯一的问题是当小于30时，我有第一个结果，然后是“缺失值，缺失值，缺失值”，

我无法摆脱缺失值的文字？

我试图在脚本之前设置变量，如

将DATA1设置为缺失值要么将DATA1设置为“” 甚至将DATA1设置为“0”

但没有运气，我知道我的脚本可能有意义，我确信有更好的方法来编写脚本，比如可能使用“重复？”

更新：告诉应用程序“Safari” 做JavaScript“var outPut = []; var arr = document.getElementsByClassName（'sortable DATAId'）; for（var i in arr）{outPut.push（arr [i] .innerHTML）}; outPut;”在文件1中 - ＆GT; {“

只需将所有元素放入数组中，使用javascript循环获取每个元素的innerHtml。

输出将是一个列表，使用此列表来获取项目而不是具有超过30个变量。

set allData to my getInputByClass2("sortable DATAId")
-- to get the tenth value, use this --> item 10 of allData 

to getInputByClass2(theClass) -- this return a list of values
    tell application "Safari"
        set r to do JavaScript "var outPut=[]; var arr=document.getElementsByClassName('" & theClass & "');for (var i in arr) {outPut.push(arr[i].innerHTML)};outPut;" in document 1
    end tell
    return strings of r --- this remove all 'Missing Value' from a list of strings
end getInputByClass2

如果要限制列表的长度，请使用此

set allData to my getInputByClass2(theClass, 30) -- 30 values maximum
-- to get the tenth value in the list, use this --> item 10 of allData 

to getInputByClass2(theClass, num) --this return a list of values
    tell application "Safari"
        set r to do JavaScript "var n=" & num & "; var outPut=[]; var arr=document.getElementsByClassName('" & theClass & "');var tLen=arr.length; if (n>tLen) {n=tLen;}; for (var i = 0; i < n; i++) {outPut.push(arr[i].innerHTML)}; outPut;" in document 1
    end tell
    return strings of r --- this remove all 'Missing Value' from a list of strings
end getInputByClass2

更新，missing value来自没有innerHTML的元素。

要从字符串列表中删除missing value，请使用此语法（set myList to strings of someList）。

我更新了脚本。

AppleScript摆脱了缺失的价值
