      发现wordpress慢是一个很大的问题,特开一博来总结优化的相关方法,介于我也是在优化中更新的,此文会长期更新。

一、优化博客中插件加载的js位置。

      很多插件在header中注册了js脚本,但希望脚本放在footer部分加载,如果修改插件可能会影响插件的升级,下面的方法来自于stackoverflow : How to put my javascript in the footer
【方法】把下面的代码添加到 主题中的functions.php中

remove_action('wp_head', 'wp_print_scripts');
remove_action('wp_head', 'wp_print_head_scripts', 9);
remove_action('wp_head', 'wp_enqueue_scripts', 1);
add_action('wp_footer', 'wp_print_scripts', 5);
add_action('wp_footer', 'wp_enqueue_scripts', 5);
add_action('wp_footer', 'wp_print_head_scripts', 5);
Copy after login

N、其它技巧

1、博客中投放了百度广告,延迟异步加载的方法:现在header中加一个全局变量

var onLoadCalls = [];
Copy after login

再在小工具中或其它部分

View Code JAVASCRIPT

onLoadCalls.push(function(){
    loadScript("http://cpro.baidu.com/cpro/ui/c.js",function(){
         BAIDU_CLB_DUP2_fillSlotAsync('u432452', 'sidebar-ad'); //sidebar-ad为广告展示的div#id
    });
});
Copy after login

接下来在尾部的js代码中添加如下代码

function loadScript(src, callback){
    var doc = document,
        body = doc.body,
        //创建一个新script来加载
        script = doc.createElement('script');
 
    script.type = 'text/javascript';
    script.src = src;
    script.onerror = script.onload = script.onreadystatechange = function(e){
        e = e || window.event;
        if(!script.readyState || /loaded|complete/.test(script.readyState) || e === 'error'){
            callback(src);
            script.onerror = script.onload = script.onreadystatechange = null;
        }
    };
    body.appendChild(script);
}
 
$(document).ready(function(){
    if(onLoadCalls && onLoadCalls.length){
        $.each(onLoadCalls, function(index, fn){
            fn.call(null, $);
        });
    }
});
Copy after login
