In practical applications, we may often need to remove duplicate elements in the array. The following is the implementation of JavaScript array deduplication:
<script language="javascript"><!--/*Method to determine whether an element exists in the array*/function isExistInArr(_array, _element){if(!_array || !_element) return false;if(!_array.length){return (_array == _element);}for(var i=0; i<_array.length; i++){if(_element == _array[i]) return true;}return false;}/*Method to remove duplicate elements in the array*/function distinct(_array){if(!_array || !_array.length) return _array;var newArray = new Array();for(var i=0; i<_array.length; i++){var oEl = _array[i];if(!oEl || this.isExistInArr(newArray, oEl)) continue;newArray[newArray.length] = oEl;}return newArray;}var origArr = [1,2,3,4,1,4,1,3];origArr = distinct(origArr);alert(origArr);//--></script>The above method of removing duplicate elements of arrays in JavaScript is the entire content I have shared with you. I hope you can give you a reference and I hope you can support Wulin.com more.
