你可以尝试使用像jLinq这样的框架——下面是一个使用jLinq的代码示例

var results = jLinq.from(data.users)
.startsWith("first", "a")
.orEndsWith("y")
.orderBy("admin", "age")
.select();

const y = 'search text';
const a = [{key: "x", "val: "y"},  {key: "d", "val: "z"}]
const data = a.filter(res => {
        return(JSON.stringify(res).toLocaleLowerCase()).match(y.toLocaleLowerCase());
});

你可以使用Array.prototype.filter方法:

var newArray = homes.filter(function (el) {
  return el.price <= 1000 &&
         el.sqft >= 500 &&
         el.num_of_beds >=2 &&
         el.num_of_baths >= 2.5;
});

生活例子:

var obj = { 'homes': [{ "home_id": "1", "price": "925", "sqft": "1100", "num_of_beds": "2", "num_of_baths": "2.0", }, { "home_id": "2", "price": "1425", "sqft": "1900", "num_of_beds": "4", "num_of_baths": "2.5", }, // ... (more homes) ... ] }; // (Note that because `price` and such are given as strings in your object, // the below relies on the fact that <= and >= with a string and number // will coerce the string to a number before comparing.) var newArray = obj.homes.filter(function (el) { return el.price <= 1000 && el.sqft >= 500 && el.num_of_beds >= 2 && el.num_of_baths >= 1.5; // Changed this so a home would match }); console.log(newArray);

该方法是新的ECMAScript第5版标准的一部分，可以在几乎所有现代浏览器中找到。

对于IE，为了兼容性，你可以包含以下方法:

if (!Array.prototype.filter) {
  Array.prototype.filter = function(fun /*, thisp*/) {
    var len = this.length >>> 0;
    if (typeof fun != "function")
      throw new TypeError();

    var res = [];
    var thisp = arguments[1];
    for (var i = 0; i < len; i++) {
      if (i in this) {
        var val = this[i];
        if (fun.call(thisp, val, i, this))
          res.push(val);
      }
    }
    return res;
  };
}

我更喜欢下划线框架。它提出了许多有用的对象操作。 你的任务:

var newArray = homes.filter(
    price <= 1000 & 
    sqft >= 500 &
    num_of_beds >=2 & 
    num_of_baths >= 2.5);

可以像这样覆盖:

var newArray = _.filter (homes, function(home) {
    return home.price<=1000 && sqft>=500 && num_of_beds>=2 && num_of_baths>=2.5;
});

希望对大家有用!

The simplest way to search a specific value in an Array of Object
--------------------------------------------------------------------

filter() -> uses a callback function the return value of which decides what will be returned in the filtered array. If the return value is true, the item is included in the resultant array.

includes() -> searches for something in an array of items using == equality
**

       const words = [{id:1,name:"tim"},{id:2,name:"morgon"}]
        
          function searchHandler(enteredString){
          const formatedString = enteredString.toLowerCase();
          const result = words.filter(data=> data?.name?.includes(formatedString));
          console.log(result);
    }
