问题描述

我想以初学者的身份理解这段代码.大多数是红色字体.他们正在采用哪个网页价值?

i want to understand this piece of code as i m a beginner.Mostly these red color fonts. they are taking which page value?

$(function() {
        $("#title").blur(function() { QuestionSuggestions(); });    
});

function QuestionSuggestions() {
    var s = $("#title").val();            
    if (s.length > 2 && !($("#title").hasClass('edit-field-overlayed'))) {
         document.title = s + " - Stack Overflow";
         $("#question-suggestions").load("/search/titles?like=" + escape(s));
    }
}

推荐答案

function QuestionSuggestions() {
        var s = $("#title").val(); // Here we take the value of element with ID "title"   
        // If the length of the title is bigger than 2 or 
        // the element doesn't have 'edit-field-overlayed' class      
        if (s.length > 2 && !($("#title").hasClass('edit-field-overlayed'))) {
            // we set the title of the document as <title>[our old title] - Stack Overflow</title>
            document.title = s + " - Stack Overflow";

            // Load data from the server and place the returned HTML into the matched element.
            $("#question-suggestions").load("/search/titles?like=" + escape(s));
        }
    }

如果您ID为title的元素的标题超过2个，则说我的标题"，并且没有类编辑字段覆盖"，我们将页面标题更改为我的标题-堆栈溢出"并加载html/通过查询URL http://yoursite.tld/search/titles?like = My％20title

If you element with id title has longer title than 2, lets say "My title" and there is no class "edit-field-overlayed" we change the page title to "My title - Stack Overflow" and load html/text in element "#question-suggestions" by querying the URL http://yoursite.tld/search/titles?like=My%20title
