是否有一个快速和简单的方法来编码JavaScript对象到字符串，我可以通过GET请求传递?
没有jQuery，没有其他框架-只有纯JavaScript:)
当前回答
URLSearchParams看起来不错，但是对于嵌套对象来说行不通。
试着使用
encodeURIComponent(JSON.stringify(object))

const buildSortedQuery = (args) => { 返回种(args) .sort () .map(key => { 返回window.encodeURIComponent(关键) + ' = ' + window.encodeURIComponent (args(例子)); }) . join (' & '); }; console.log (buildSortedQuery ({ Foo:“你好”， 栏:“100%” })); / /酒吧= 100% 25 foo =你好% 20
jQuery有一个函数jQuery.param()。如果你已经在使用它，你可以使用这个:
例子:
var params = { width:1680, height:1050 };
var str = jQuery.param( params );
STR现在包含宽度=1680&高度=1050。
如果您需要发送任意对象，那么GET是一个坏主意，因为有限制的url长度，用户代理和web服务器将接受。我的建议是建立一个名称-值对数组来发送，然后建立一个查询字符串:
function QueryStringBuilder() {
var nameValues = [];
this.add = function(name, value) {
nameValues.push( {name: name, value: value} );
};
this.toQueryString = function() {
var segments = [], nameValue;
for (var i = 0, len = nameValues.length; i < len; i++) {
nameValue = nameValues[i];
segments[i] = encodeURIComponent(nameValue.name) + "=" + encodeURIComponent(nameValue.value);
}
return segments.join("&");
};
}
var qsb = new QueryStringBuilder();
qsb.add("veg", "cabbage");
qsb.add("vegCount", "5");
alert( qsb.toQueryString() );

我对JSON stringfier进行了比较，结果如下:
JSON: {"_id":"5973782bdb9a930533b05cb2","isActive":true,"balance":"$1,446.35","age":32,"name":"Logan Keller","email":"logankeller@artiq.com","phone":"+1 (952) 533-2258","friends":[{"id":0,"name":"Colon Salazar"},{"id":1,"name":"French Mcneil"},{"id":2,"name":"Carol Martin"}],"favoriteFruit":"banana"}

其中最短的是URL对象表示法。
