validating IP address URL in catalog variable

[Amit Dey1]

Hi I have a requirement to validate this type of IP address in catalog variable , example - http://10.68.6.238 , so which regular expression to use for this 

[lundsholm]

Here's an example that I found on https://www.oreilly.com/library/view/regular-expressions-cookbook/9780596802837/ch07s16.html:

var regex = /^http:\/\/(?:[0-9]{1,3}\.){3}[0-9]{1,3}$/;

You can use RegExr to try it out:

Hi lundsholm , there was already a catalog onsubmit  client script which was only getting URL field validation for that particular field , I just add your regex on that OR condition - bold parts are changes done by me

script below -

function onSubmit() {
var data = '{"fields":[' +
'{"fieldName":"cat_variable_name"}]}';

var json = JSON.parse(data);
var isValid = true;
var fieldValuefields = [];
var fieldName = '';
for (var i = 0; i < json.fields.length; i++) {
fieldName = json.fields[i].fieldName;
var fieldValue = g_form.getValue(fieldName);
g_form.hideFieldMsg(fieldName, true);
var varValue = g_form.getValue(fieldName);
var re = /^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/;
var reipurl = /^http:\/\/(?:[0-9]{1,3}\.){3}[0-9]{1,3}$/;
if (fieldValue.toLowerCase().trim() == "na" || fieldValue.toLowerCase().trim() == "n/a") {
g_form.hideErrorBox(fieldName);
}
else if ((!re.test(fieldValue) || !reipurl.test(fieldValue)) && (fieldValue != '')) {
g_form.showErrorBox(fieldName, "Please enter valid URL");
fieldValuefields.push(g_form.getLabelOf(fieldName));
isValid = false;
} else {
g_form.hideErrorBox(fieldName);
}
}

if (isValid == false) {

alert("Please check URL for fields " + "'" + fieldValuefields + "'", 'error');
return false;
}
