搜索Json数组

Question

[
    {"value":"uk-icon-adjust","title":"Adjust","url":"#", "text":""},
    {"value":"uk-icon-adn","title":"Adn","url":"#", "text":""},
    {"value":"uk-icon-align-center","title":"Align center","url":"#", "text":""},
    {"value":"uk-icon-align-justify","title":"Align justify","url":"#", "text":""},
    {"value":"uk-icon-align-left","title":"Align left","url":"#", "text":""}
]

我想在这个json数组中搜索特定的标题。但问题是，我想用正则表达式进行搜索。例如：sb搜索“ad”->函数应该返回前两个json字符串（Adjust和Adn）。

我不知道，现在设置一个javascript函数可以实现这一点。

一些想法？

试试看：

var array = [
    {"value":"uk-icon-adjust","title":"Adjust","url":"#", "text":""},
    {"value":"uk-icon-adn","title":"Adn","url":"#", "text":""},
    {"value":"uk-icon-align-center","title":"Align center","url":"#", "text":""},
    {"value":"uk-icon-align-justify","title":"Align justify","url":"#", "text":""},
    {"value":"uk-icon-align-left","title":"Align left","url":"#", "text":""}
  ],
  searchString = 'ad',
  searchRegExp = new RegExp(searchString , 'i'); // 'i' makes the RegExp ignore case

var result = array.filter(function(e){ // Filter out any items that don't pass the
    return searchRegExp.test(e.title); //  RegExp test.
});

结果：

[
    {"value":"uk-icon-adjust","title":"Adjust","url":"#","text":""},
    {"value":"uk-icon-adn","title":"Adn","url":"#","text":""}
]

如果只想要标题数组,那么可以映射结果,如下所示：

var titles = result.map(function(e){
    return e.title;
});

["Adjust", "Adn"]

var result = array.filter(function(e){
    return searchRegExp.test(e.title);
}).map(function(e){
    return e.title;
});
