URL 在 jQuery 中为 AJAX 请求编码一个字符串 [英] URL Encode a string in jQuery for an AJAX request

问题描述

我正在我的应用程序中实施 Google 的即时搜索.我想在用户输入文本时触发 HTTP 请求.我遇到的唯一问题是，当用户进入名字和姓氏之间的空格时，该空格不会被编码为 +，从而破坏了搜索.我怎样才能用 + 替换空格，或者只是安全地对字符串进行 URL 编码?

I'm implementing Google's Instant Search in my application. I'd like to fire off HTTP requests as the user types in the text input. The only problem I'm having is that when the user gets to a space in between first and last names, the space is not encoded as a +, thus breaking the search. How can I either replace the space with a +, or just safely URL Encode the string?

$("#search").keypress(function(){       
    var query = "{% url accounts.views.instasearch  %}?q=" + $('#tags').val();
    var options = {};
    $("#results").html(ajax_load).load(query);
});

推荐答案

尝试 encodeURIComponent.

通过用一个、两个、三个或四个表示字符的 UTF-8 编码的转义序列替换某些字符的每个实例来对统一资源标识符 (URI) 组件进行编码(对于由以下内容组成的字符，只有四个转义序列)两个代理"字符).

Encodes a Uniform Resource Identifier (URI) component by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two "surrogate" characters).

示例:

var encoded = encodeURIComponent(str);
