Question

我的.js文件如下：

var LoginData=([
        {
            "PL":"ccc","browser":"firefox","execute":"n",   
        },
        {
            "PL":"aaa","browser":"firefox","execute":"n",   
        },
        {
            "PL":"bbb","browser":"firefox","execute":"n",   
        },
        {
            "PL":"ddd","browser":"firefox","execute":"n",   
    
]);

我需要搜索“PL”之类的字符串：“ccc”，“browser”：“firefox”，“execute”：“n” 并替换为“PL”：“ccc”，“browser”：“firefox”，“execute”：“y”。我尝试使用replace命令，但它插入了????????可能是因为这是.js文件。

请让我知道它可行吗？

Answer 1

通常这样的事情应该有效：

$filename = 'C:\path\to\your.js'

$srch = '"PL":"ccc","browser":"firefox","execute":"n"'
$repl = '"PL":"ccc","browser":"firefox","execute":"y"'

(Get-Content $filename) -replace $srch, $repl |
  Set-Content $filename -Encoding ASCII

使用Powershell搜索和替换
