File path validation

[William08]

Hi all,

Need a help on file path validation for below patterns. Could anyone please help on this

x:\File

\File\File\ or
\File\File or
\File\\File etc

Thanks in advance

Hi @William08 ,

you can use regular expressions (regex) to define the validation rules.

// Define the file path patterns
var patterns = [
  /^x:\\[a-zA-Z0-9_]+$/,
  /^\\[a-zA-Z0-9_]+(\\[a-zA-Z0-9_]+)+$/,
  /^\\[a-zA-Z0-9_]+(\\[a-zA-Z0-9_]+)*$/,
  /^\\[a-zA-Z0-9_]+\\\\[a-zA-Z0-9_]+$/
];

// Example file paths to validate
var filePaths = [
  'x:\\File',
  '\\File\\File\\',
  '\\File\\File',
  '\\File\\\\File'
];

// Validate file paths against the patterns
filePaths.forEach(function(filePath) {
  var isValid = patterns.some(function(pattern) {
    return pattern.test(filePath);
  });

  gs.info('File path: ' + filePath + ' - Valid: ' + isValid);
});

Tested Output:

The patterns array contains the regular expressions that define the file path patterns you provided. The filePaths array includes example file paths that you want to validate.

The code uses the test() method of each pattern to check if a file path matches any of the defined patterns. If a match is found, the file path is considered valid. The result is logged using gs.info().

Hi Shravan,

I modified and tried but it is not working could you please help!

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
 
var patterns = [
  /^E:\[a-zA-Z0-9_]+$/,
  /^\[a-zA-Z0-9_]+(\[a-zA-Z0-9_]+)+$/,
  
];

var filePaths =  g_form.getValue('folder_path');
alert(filePaths);
for (var i = 0; i < patterns.length; i++) {
  var pattern = patterns[i];
  if (pattern.test(filePaths)) {
    alert("matched");
  } else {
   alert("missmatched");
  }
}

}

It should accept the below example patterns

E:\Test

/data1/data2/data2/data2/

Hi @William08 ,

can you please update as below

 var patterns = [
        /^E:\\[a-zA-Z0-9_]+$/,
        /^\/[a-zA-Z0-9_]+(\/[a-zA-Z0-9_]+)+\/$/,
    ];

Hi @Sai Shravan 

It is throwing alert as missmatched.
