html静态页面引入公共html页面

不用模板引擎在普通静态html页面导入公共的html页面,比如header.html, footer.html, 可以这样做,自己写了一个include.js

(function(window, document, undefined) {  
    var Include39485748323 = function() {}  
    Include39485748323.prototype = {  
        //倒序循环  
        forEach: function(array, callback) {  
            var size = array.length;  
            for(var i = size - 1; i >= 0; i--){  
                callback.apply(array[i], [i]);  
            }  
        },  
        getFilePath: function() {  
            var curWwwPath=window.document.location.href;  
            var pathName=window.document.location.pathname;  
            var localhostPaht=curWwwPath.substring(0,curWwwPath.indexOf(pathName));  
            var projectName=pathName.substring(0,pathName.substr(1).lastIndexOf('/')+1);  
            return localhostPaht+projectName;  
        },  
        //获取文件内容  
        getFileContent: function(url) {  
            var ie = navigator.userAgent.indexOf('MSIE') > 0;  
            var o = ie ? new ActiveXObject('Microsoft.XMLHTTP') : new XMLHttpRequest();  
            o.open('get', url, false);  
            o.send(null);  
            return o.responseText;  
        },  
        parseNode: function(content) {  
            var objE = document.createElement("div");  
            objE.innerHTML = content;  
            return objE.childNodes;  
        },  
        executeScript: function(content) {  
            var mac = /<script>([\s\S]*?)<\/script>/g;  
            var r = "";  
            while(r = mac.exec(content)) {  
                eval(r[1]);  
            }  
        },  
        getHtml: function(content) {  
            var mac = /<script>([\s\S]*?)<\/script>/g;  
            content.replace(mac, "");  
            return content;  
        },  
        getPrevCount: function(src) {  
            var mac = /\.\.\//g;  
            var count = 0;  
            while(mac.exec(src)) {  
                count++;  
            }  
            return count;  
        },  
        getRequestUrl: function(filePath, src) {  
            if(/http:\/\//g.test(src)){ return src; }  
            var prevCount = this.getPrevCount(src);  
            while(prevCount--) {  
                filePath = filePath.substring(0,filePath.substr(1).lastIndexOf('/')+1);  
            }  
            return filePath + "/"+src.replace(/\.\.\//g, "");  
        },  
        replaceIncludeElements: function() {  
            var $this = this;  
            var filePath = $this.getFilePath();  
            var includeTals = document.getElementsByTagName("include");  
            this.forEach(includeTals, function() {  
                //拿到路径  
                var src = this.getAttribute("src");  
                //拿到文件内容  
                var content = $this.getFileContent($this.getRequestUrl(filePath, src));  
                //将文本转换成节点  
                var parent = this.parentNode;  
                var includeNodes = $this.parseNode($this.getHtml(content));  
                var size = includeNodes.length;  
                for(var i = 0; i < size; i++) {  
                    parent.insertBefore(includeNodes[0], this);  
                }  
                //执行文本中的额javascript  
                $this.executeScript(content);  
                parent.removeChild(this);  
                //替换元素 this.parentNode.replaceChild(includeNodes[1], this);  
            })  
        }  
    }  
    window.onload = function() {  
        new Include39485748323().replaceIncludeElements();  
    }  
})(window, document)
