HHTjim'S 部落格

博客标题下面的ajax加载一句话

作者：matrix 发布时间：2015-01-12 分类：Wordpress 兼容并蓄

博客LOGO下面的一句话功能是照搬philna2主题弄的，点击一下就更新一句话的内容，是很久前的弄的小功能，现在回忆一下简单步骤。给需要的一位童鞋。

1.在wordpress主题的functions.php中添加代码

function HHTJimSay(){
    $Sentence =
    '
    11111
    22222
    33333
    44444
    ';
    $words = explode("\n", $Sentence);
    $word = $words[ mt_rand(1, count($words) - 2) ];
    echo $word;
}
function _exitajax(){
exit();
}
function Is_AjaxURL() {
    if((isset($_GET['do']) && $_GET['do'] == 'ajax') ) {
        return true;
    }else{
        return false;
    }
}
/**
 * 通过USER_Agent判断是否为机器人.
 */
function is_bot(){
    $bots = array('Google Bot1' => 'googlebot', 'Google Bot2' => 'google', 'MSN' => 'msnbot', 'Alex' => 'ia_archiver', 'Lycos' => 'lycos', 'Ask Jeeves' => 'jeeves', 'Altavista' => 'scooter', 'AllTheWeb' => 'fast-webcrawler', 'Inktomi' => 'slurp@inktomi', 'Turnitin.com' => 'turnitinbot', 'Technorati' => 'technorati', 'Yahoo' => 'yahoo', 'Findexa' => 'findexa', 'NextLinks' => 'findlinks', 'Gais' => 'gaisbo', 'WiseNut' => 'zyborg', 'WhoisSource' => 'surveybot', 'Bloglines' => 'bloglines', 'BlogSearch' => 'blogsearch', 'PubSub' => 'pubsub', 'Syndic8' => 'syndic8', 'RadioUserland' => 'userland', 'Gigabot' => 'gigabot', 'Become.com' => 'become.com','Bot'=>'bot','Spider'=>'spider','yinheli_for_test'=>'dFirefox');
    $useragent = $_SERVER['HTTP_USER_AGENT'];
    foreach ($bots as $name => $lookfor) {
        if (stristr($useragent, $lookfor) !== false) {
            return true;
            break;
        }
    }
}
if(Is_AjaxURL() && !is_bot()){//存在_GET且不是机器
add_action('Ready','HHTJimSay');
add_action('Ready', '_exitAjax', 9999);
}
do_action( 'Ready');

说明：
用于ajax后台提取一句话函数
4-7行处自己添加需要显示的一句话

2.在header.php中，加载完jq之后的位置添加js代码

var blogURL="https://www.hhtjim.com";//网站域名  
$(function(){  
    function o(v){  
        url=v.u?v.u:blogURL+"?do=ajax";  
        if(v.fn){  
            var nowTime = new Date().getTime();  
            url+="&action="+v.fn+"&t="+nowTime  
        }  
        type=v.m?v.m:"GET";  
        data=v.d?v.d:null;  
        dataType=v.dt?v.dt:"html";  
        beforeSend=v.b?v.b:null;  
        error=v.e?v.e:function(){  
            alert(lang.commonError);  
            document.body.style.cursor="auto"  
        };  
        success=v.s?v.s:function(w){  
            alert(w)  
        };  
        $.ajax({  
            url:url,type:type,data:data,dataType:dataType,beforeSend:beforeSend,error:error,success:success  
        })  
    }  

    function u(){  
        var v=false;  
        var x=document.getElementById('HHTJimSay') ? $("#HHTJimSay") : $("#HHTJimSay_s") ;  
        var w="loading";  
        x.click(function(){  
            if(v){  
                return false  
            }  
            var z=function(){  
                x.hide(0,function(){  
                    x.attr('title','').html("").addClass(w).show();//0秒后出现漏斗  

                });  
                v=true  
            };  
            var y=function(){  
                x.html(lang.commonError);  
                x.removeClass(w);  
                v=false  
            };  
            var A=function(B){  
                setTimeout(function(){  
                    x.hide(0);  
                    x.attr('title','点击这里获取更新').html(B).removeClass(w).fadeIn("slow"); //show(300)改fadeIn("slow") 淡入  
                    v=false  
                }  
                ,3000)//3000 漏斗出现时间  
            };  
            o({  
                b:z,e:y,s:A,fn:"HHTJimSay"  
            });  
            return false  
        })  
    }  
    u();  
    function n(){  
        var w=$("#welcome_msg");  
        var v=$("#profile");  
        var m=$("#author");  
        $("#edit_profile").toggle(function(){  
            w.slideUp(200);  
            v.slideDown(200);  
            m.select();  
            return false  
        }  
        ,function(){  
            w.slideDown(200);  
            v.slideUp(200);  
            return false  
        })  
    }  
    n();  
});  

说明：修改第一行的网站域名

3.在header.php处需要显示的位置添加代码

<span id="HHTJimSay_s" title="点击这里获取更新" style="white-space: nowrap;" class="description"><?php HHTJimSay(); ?></span>

4.在style.css中添加样式代码

#HHTJimSay_s{background:url('data:image/gif;base64,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') no-repeat 10000px 10000px;cursor:pointer;}
