jQuery gets the number that appears most in a string_jquery

Recommended reading: A tool to count the occurrences of each string in jQuery

No more nonsense, I will just post the js code for you.

//获取字符串中出现最多的数和它一共出现多少次
var str = 'asdfssaaasasasasaa'; //定义字符串
var json = {}; //定义数组用来存储每个字符元素所对应的个数
for (var i = 0; i < str.length; i++) { //遍历字符串中所有的元素
if (!json[str.charAt(i)]) { //判断当前元素是否已经在数组中存在 str.charAt(i)//当前元素
json[str.charAt(i)] = 1; //给对应数组元素中个数赋值
}
else 
{
json[str.charAt(i)]++; //给数组中元素个数赋值
}
};
var iMax = 0;//出现次数
var iIndex = '';//元素名称
for(var i in json){ //重新赋值出现最多的数据和个数
if(json[i]>iMax){
iMax = json[i];
iIndex = i;
}
}
//alert('出现次数最多的是:'+iIndex+'出现'+iMax+'次');

The above code is the jQuery introduced by the editor to get the most frequent numbers in a string. The code is simple and easy to understand. If you don’t understand anything, please leave me a message and I will get in touch with you in time.
