jQuery Check duplicated value in array
There are the Following The simple About jQuery Check duplicated value in array Full Information With Example and source code.
As I will cover this Post with live Working example to develop jQuery check duplicate values in inputs, so the Check duplicated value in array for this example is following below.
Example 1: Jquery check if array contains duplicate string
var reportRecipients = ['PAKAINFO', 'ARITY', 'PAKAINFO', 'GONDALIYA', 'JAYDEEP', 'ARITY', 'PQR'];
var memberArrData = reportRecipients.sort();
var reportCheckDuplicate = [];
for (var i = 0; i < memberArrData.length - 1; i++) {
if (memberArrData[i + 1] == memberArrData[i]) {
reportCheckDuplicate.push(memberArrData[i]);
}
}

$('#checkDuplicate').html(arr.sort().join("
"));
});
Jquery check if array contains duplicate string
To check if an array contains duplicate strings using jQuery, you can use the grep() function to create a new array that contains only the elements of the original array that occur more than once. If this new array is not empty, then the original array contains duplicate strings. Here's an example:
var myArray = ['apple', 'banana', 'cherry', 'apple', 'date', 'banana'];
var duplicates = $.grep(myArray, function(element, index){
return $.inArray(element, myArray) !== index;
});
if (duplicates.length === 0) {
console.log("The array does not contain duplicate strings.");
} else {
console.log("The array contains the following duplicate strings: " + duplicates.join(", "));
}
In the above code, the $.grep() function is used to create a new array called duplicates that contains only the elements of myArray that occur more than once. The $.inArray() function is used to check if an element is already in myArray. If an element is found in myArray but not at the current index, then it is considered a duplicate.
Finally, the if-else statement is used to check if the duplicates array is empty. If it is empty, then the original array does not contain any duplicate strings. If it is not empty, then the duplicates array contains the duplicate strings.
