具有名称的JavaScript字典 [英] JavaScript dictionary with names

问题描述

我想在javascript中创建一个字典，如下所示：

I want to create a dictionary in javascript like the following:

myMappings = [
{ "Name":10%},
{ "Phone":10%},
{ "Address":50%},
{ "Zip":10%},
{ "Comments":20%}
]

我想稍后填写一个html表，将表的标题设置为myMappings的第一列，将列的宽度设置为第二列。因为我是JS的新手，找不到干净的方式。可以一些建议吗？

I want to populate an html table later and want to set the titles of table to the first column of myMappings and the width of columns to the second. As I am new to JS, having trouble finding the clean way. Can some pls suggest?

谢谢

推荐答案

主要问题我看看你有什么是很难循环，填充一个表。

The main problem I see with what you have is that it's difficult to loop through, for populating a table.

只需使用数组：

var myMappings = [
    ["Name", "10%"], // Note the quotes around "10%"
    ["Phone", "10%"],
    // etc..
];

...这简化了访问：

... which simplifies access:

myMappings[0][0]; // column name
myMappings[0][1]; // column width

---

或者：

Alternatively:

var myMappings = {
    names: ["Name", "Phone", etc...],
    widths: ["10%", "10%", etc...]
};

并访问：

myMappings.names[0];
myMappings.widths[0];
