我有一个批处理文件,用于检查文件夹中的图片数量。 如何将此值返回给调用批处理文件的JavaScript?
dir /B /A-D /S "C:\Users\Viktor\Desktop\Images\*.jpg" | find /N /C /V ""
pause
以下是从JavaScript运行批处理文件的代码:
var file = null;
var process = null;
var args = [""];
// create an nsIFile for the executable
file = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsIFile);
file.initWithPath("C:\\Users\\Viktor\\Desktop\\file.bat");
// create an nsIProcess
process = Components.classes["@mozilla.org/process/util;1"].createInstance(Components.interfaces.nsIProcess);
process.init(file);
// Launch the process
process.run(false , args, args.length);

当您只能使用浏览器和imacros时,我不知道为什么需要这个批处理文件.js
在浏览器中打开文件夹:file:///C:/Users/Viktor/Desktop/Images/
然后在iMacros中运行此.js:
var img = new Array();
iimPlayCode("TAG POS=1 TYPE=BODY ATTR=* EXTRACT=TXT");
img = iimGetExtract().split(".jpg");
alert(img.length-1);

您可以使用以下语法将 dir 命令的结果重定向到新的HTML文件中:
structure(list(SAMPN = c(" 827", " 827", " 1133", " 1133",
" 1133", " 1133", " 1133", " 1133", " 1857", " 1857", " 1857"
), HHVEH = c(3, 3, 2, 2, 2, 2, 2, 2, 3, 3, 3), PERNO = structure(c(2L,
4L, 4L, 3L, 3L, 5L, 1L, 1L, 3L, 2L, 3L), .Label = c("1", "2",
"3", "4", "5", "6", "7"), class = "factor")), row.names = c(NA,
-11L), groups = structure(list(SAMPN = c(" 827", " 1133", " 1857"
), .rows = list(1:2, 3:8, 9:11)), row.names = c(NA, -3L), class = c("tbl_df",
"tbl", "data.frame"), .drop = TRUE), class = c("grouped_df",
"tbl_df", "tbl", "data.frame"))
SAMPN HHVEH PERNO mode.car
<chr> <dbl> <fct>
1 " 827" 3 2 2
2 " 827" 3 4 2
3 " 1133" 2 4 2
4 " 1133" 2 3 2
5 " 1133" 2 3 NA
6 " 1133" 2 5 NA
7 " 1133" 2 1 NA
8 " 1133" 2 1 NA
9 " 1857" 3 3 2
10 " 1857" 3 2 2
11 " 1857" 3 3 2
这会将.bat结果写入您的html。

要将变量值返回给JavaScript,请尝试从找到的变量值作为参数重新启动该批处理的JavaScript文件。在JavaScript文件中添加一个开关,以便在定义了该参数后再次绕过调用批处理。
