javascript - Google Blogger 的编号页面导航在搜索结果页面上不起作用

Question

我在我的 Blogger 上添加了一个带编号的页面导航脚本，它适用于除搜索结果页面之外的所有页面 (当我搜索帖子时显示结果的页面) - - 它在该页面上显示默认的“以前的帖子和较新的帖子”。

实际上我对 JavaScript 了解不多，因此我需要帮助来修改给定的 JavaScript，以便它也像 Wordpress 一样在搜索结果页面上工作。

我很乐意提供任何其他需要的详细信息。

提前致谢...:-)

Answer 1

首先你必须修改搜索框，改变表单 Action 属性

action="/search/max-results=12"

到

action="/search/"    

将 max-results 参数指定为隐藏的 input 字段

<input type='hidden' name='max-results' value="12" />

其次，在上面的 JavaScript 代码中，搜索以下行 -

if (thisUrl.indexOf("?q=") == -1 && thisUrl.indexOf(".html") == -1)

并将其替换为 -

if (thisUrl.indexOf(".html") == -1)

上述条件(又名 thisUrl.indexOf("?q=") == -1)停止脚本在带有名为 q 的查询参数的页面上工作> 在网址中

编辑 1:在搜索结果页面上显示正确的页码

在上面的代码中搜索下面的函数-

function redirectpage(numberpage) {
    jsonstart = (numberpage - 1) * perPage;
    noPage = numberpage;
    var nameBody = document.getElementsByTagName('head')[0];
    var newInclude = document.createElement('script');
    newInclude.type = 'text/javascript';
    newInclude.setAttribute("src", home_page + "feeds/posts/summary?start-index=" + jsonstart + "&max-results=1&alt=json-in-script&callback=finddatepost");
    nameBody.appendChild(newInclude)
}

将其替换为 -

function redirectpage(numberpage) {
    jsonstart = (numberpage - 1) * perPage;
    noPage = numberpage;
    var nameBody = document.getElementsByTagName('head')[0];
    var newInclude = document.createElement('script');
    newInclude.type = 'text/javascript';
    if(urlactivepage.indexOf("?q=") == -1){
        newInclude.setAttribute("src", home_page + "feeds/posts/summary?start-index=" + jsonstart + "&max-results=1&alt=json-in-script&callback=finddatepost");
    } else {
        newInclude.setAttribute("src", home_page + "feeds/posts/summary?start-index=" + jsonstart + "&alt=json-in-script&q="+ urlactivepage.split("?")[1].split("q=")[1].split("&")[0] +"&callback=finddatepost");  
    }
    nameBody.appendChild(newInclude);
}

然后搜索下面的代码块——

function pagecurrentg() {
    var thisUrl = urlactivepage;
    if (thisUrl.indexOf("/search/label/") != -1) {
        if (thisUrl.indexOf("?updated-max") != -1) {
            postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?updated-max"))
        } else {
            postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?&max"))
        }
    }
    if (thisUrl.indexOf("?q=") == -1 && thisUrl.indexOf(".html") == -1) {
        if (thisUrl.indexOf("/search/label/") == -1) {
            currentPage = "page";
            if (urlactivepage.indexOf("#PageNo=") != -1) {
                currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
            } else {
                currentPageNo = 1
            }
            document.write("<script src=\"" + home_page + "feeds/posts/summary?max-results=1&alt=json-in-script&callback=totalcountdata\"><\/script>")
        } else {
            currentPage = "label";
            if (thisUrl.indexOf("&max-results=") == -1) {
                perPage = 20
            }
            if (urlactivepage.indexOf("#PageNo=") != -1) {
                currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
            } else {
                currentPageNo = 1
            }
            document.write('<script src="' + home_page + 'feeds/posts/summary/-/' + postLabel + '?alt=json-in-script&callback=totalcountdata&max-results=1" ><\/script>')
        }
    }
}

并将其替换为 -

function pagecurrentg() {
    var thisUrl = urlactivepage;
    if (thisUrl.indexOf("/search/label/") != -1) {
        if (thisUrl.indexOf("?updated-max") != -1) {
            postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?updated-max"))
        } else {
            postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?&max"))
        }
    }
    if (thisUrl.indexOf(".html") == -1) {
        if (thisUrl.indexOf("/search/label/") == -1) {
            currentPage = "page";
            if (urlactivepage.indexOf("#PageNo=") != -1) {
                currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
            } else {
                currentPageNo = 1
            }
            if(thisUrl.indexOf("q=") == -1){
                document.write("<script src=\"" + home_page + "feeds/posts/summary?max-results=1&alt=json-in-script&callback=totalcountdata\"><\/script>")
            } else {
                document.write("<script src=\"" + home_page + "feeds/posts/summary?q=" + thisUrl.split("?")[1].split("q=")[1].split("&")[0] + "&alt=json-in-script&callback=totalcountdata\"><\/script>")
            }
       } else {
            currentPage = "label";
            if (thisUrl.indexOf("&max-results=") == -1) {
                perPage = 20
            }
            if (urlactivepage.indexOf("#PageNo=") != -1) {
                currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
            } else {
                currentPageNo = 1
            }
            document.write('<script src="' + home_page + 'feeds/posts/summary/-/' + postLabel + '?alt=json-in-script&callback=totalcountdata&max-results=1" ><\/script>')
        }
    }
}

然后搜索下面的代码块

function finddatepost(root) {
    post = root.feed.entry[0];
    var timestamp1 = post.published.$t.substring(0, 19) + post.published.$t.substring(23, 29);
    var timestamp = encodeURIComponent(timestamp1);
    if (currentPage == "page") {
        var pAddress = "/search?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
    } else {
        var pAddress = "/search/label/" + postLabel + "?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
    }
    location.href = pAddress
}

并将其替换为 -

function finddatepost(root) {
    post = root.feed.entry[0];
    var timestamp1 = post.published.$t.substring(0, 19) + post.published.$t.substring(23, 29);
    var timestamp = encodeURIComponent(timestamp1);
    if (currentPage == "page") {
        if(urlactivepage.indexOf("?q=") == -1){
                var pAddress = "/search?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
        } else {
                var pAddress = "/search?updated-max=" + timestamp + "&q="+ urlactivepage.split("?")[1].split("q=")[1].split("&")[0] +"&max-results=" + perPage + "#PageNo=" + noPage
            }
        } else {
        var pAddress = "/search/label/" + postLabel + "?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
    }
    location.href = pAddress
}

在所有这些代码块中，我添加了额外的条件来处理查询参数条件。如果您感到困惑，那么整个新文件看起来像 - this .可以在此处检查一个工作示例 - https://prayagverma.blogspot.com/?q=Tweet .

注意:我还从上面的 JSON API 调用中删除了 max-results，因为它们影响了 openSearch$totalResults.$t 参数(它通常不应该)
