javascript - URL 为 AJAX 请求在 jQuery 中编码一个字符串

Question

我正在我的应用程序中实现 Google 的即时搜索。我想在用户输入文本输入时触发 HTTP 请求。我遇到的唯一问题是，当用户到达名字和姓氏之间的空格时，该空格没有被编码为 +，从而中断了搜索。如何用 + 替换空格，或者只是安全地对字符串进行 URL 编码？

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

试试 encodeURIComponent .

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).

例子:

var encoded = encodeURIComponent(str);
