With this statement:
有了这个声明：
var arrDescription = description.split(";");
you will get an array with all the values. For more info on splitcheck the following link.
你会得到一个包含所有值的数组。有关split检查以下链接的更多信息。
you can even join them afterwards :
你甚至可以事后加入他们：
printf(arrDescription.join(" "));

You can do it with String.split()but in this case it's simpler to use String.replace():
你可以这样做，String.split()但在这种情况下使用更简单String.replace()：
var description="Name:John;EmployeeID:2;Salary:00;Address:London";
description = description.replace(/;/g, '\n').replace(/:/g, ': ');
/*
"Name: John
EmployeeID: 2
Salary: 00
Address: London"
*/

If you want the result as an object, try:
如果您希望结果作为对象，请尝试：
var f = function (str) {
var x = {}, key2label = { EmployeeID: 'Employee Id' };
str.replace(/(.+?):(.+?)(;|$)/g, function (match, key, value) {
key = key2label[key] || key;
x[key] = value;
});
return x;
};
If a simple string is needed, but you still need to replace keys:
如果需要一个简单的字符串，但您仍然需要替换键：
var f2 = function (str) {
var key2label = { EmployeeID: 'Employee Id' };
return str.replace(/(.+?):(.+?)(;|$)/g, function (match, key, value, semi) {
key = key2label[key] || key;
return key + ': ' + value + (semi ? '\n' : '');
});
};
If you really didn't mean to replace keys, this will do it:
如果您真的不想更换密钥，则可以这样做：
var f3 = function (str) {
return str.split(':').join(': ').split(';').join('\n');
};

You can probable try like this to display.
你可以试试这样显示。
var description="Name:John;EmployeeID:2;Salary:00;Address:London";
var arr=new Array();
arr=description.split(";");
for(var i=0;i<arr.length;i++)
document.writeln("<h4>"+arr[i]+"</h4>");

Yes.
是的。
You first should spliton the semicolon ;. Loop through those results, and spliteach result on each colon :.
你首先应该split在分号上;。循环遍历这些结果，以及split每个冒号上的每个结果:。
You will have to build the result by hand.
您将不得不手动构建结果。

var description="Name:John;EmployeeID:2;Salary:$8000;Address:London"; var splitted = description.split(";");
var description="Name:John;EmployeeID:2;Salary:$8000;Address:London"; var splitted = description.split(";");
for(var i = 0; i < splitted.length; i++) { document.write(splitted[i] + ""); }
for(var i = 0; i < splitted.length; i++) { document.write(splitted[i] + ""); }
