产生不重复的随机数

/*count : 随机数的个数numericalRange : 随机数范围*/function NonRepeatedRandomVal( count, numericalRange ){var array = [];var i = 0;var tempArray = numericalRange.split('~');var x1 = parseInt( tempArray[0] );var x2 = parseInt( tempArray[1] );if (x2 - x1 < count) {alert('产生的随机数个数不能小于最大范围！');return false;}while(i < count){var flag = true;var temp = parseInt( x1 + Math.random() * (x2 - x1) );for(var i=0; i<array.length; i++){if (array[i] == temp) {flag = false;break;}}if (flag) {array.push(temp);i++;}}return array;}//测试例子var array = NonRepeatedRandomVal( 100, '0~100' );if (array) {console.log( array.sort(function(a, b){return a - b;}) );}
