JQuery模板插件jquery.tmpl-动态ajax扩展

标签:
JQuery

在上一篇JQuery模板插件-jquery.tmpl中介绍了这款插件。有时我们需要去动态的ajax去加载模板,或者数据,根据url参数或者其他信息加载不同的模板,数据。在我的某个项目中有这个需求,所以特地写成jquery工具函数,加入了本地数据和ajax数据加载模板,数据的方式。

参数说明:

Tmpl: function(template, data, fun)

1:template:

1): url: 为ajax的加载url,ajax当且仅当remote= true时候加载。

2):data: 为ajax加载参数

3) templateSelector: 为本地模板选择器,当且仅当remote= false时使用

4) remote: true为ajax,false为本地数据,

5) cache: 指示是否对模板缓存。

2:data:

1): url: 为ajax的加载url,ajax当且仅当remote= true时候加载。

2):data: 为ajax加载参数

3) templateData: 为本地数据,当且仅当remote= false时使用

4) remote: true为ajax,false为本地数据,

5) cache: 指示是否对模板缓存。

3:fun为回调函数:

fun(jquery.tmpl对象,模板script,数据);

具体代码如下:

View Code    ; (function($) {       $.extend({           Tmpl_Data: function(te, data, fun, templatecache) {               data = jQuery.extend({ data: "", url: "", templateData: {}, remote: true, cache: true }, data);               if (!data.remote) {                   fun(te.tmpl(data.templateData), te, data.templateData);                   if (!templatecache) {                       te.remove();                   }                   return;               }               var da = te.data("objdata");               if (data.cache && da != null && da != undefined) {                   fun(te.tmpl(da), te, da);                   if (!templatecache) {                       te.remove();                   }                   return;               }                $.ajax({                   type: "GET",                   data: data.data,                   url: data.url,                   dataType: "json",                   cache: false,                   context: { template: te, data: data },                   success: function(tmpldata) {                       fun(this.template.tmpl(tmpldata), this.template, tmpldata);                       if (data.cache) {                           this.template.data("objdata", tmpldata);                       }                        if (!templatecache) {                           this.template.remove();                       }                   },                   error: function(e) {                       throw "get data error(" + this.data.url + "?" + this.data.data + "):" + e;                   }               });            },            JquerySelecotrCharChange: function(str) {               return str.replace(".", "\\.").replace("#", "\\#");           },            Tmpl: function(template, data, fun) {               template = jQuery.extend({ data: "", url: "", templateSelector: "", remote: true, cache: true }, template);                if (!template.remote) {                   $.Tmpl_Data($(template.templateSelector), data, fun, true);                   return;               }               var te = null;               try {                   te = $("script:[url='" + $.JquerySelecotrCharChange(template.url + "?" + template.data) + "']")               }               catch (e) {                }               if (template.cache && te != null && te.length > 0) {                   $.Tmpl_Data(te, data, fun, template.cache);                   return;               }                $.ajax({                   type: "GET",                   data: template.data,                   url: template.url,                   dataType: "html",                   cache: false,                   context: { template: template, data: data },                   error: function(e) {                       throw "get template error(" + this.template.url + "?" + this.template.data + "):" + e;                   },                   success: function(tmpltemplate) {                       var te = $('<script  type="text/x-jquery-tmpl">' + tmpltemplate + '<\/script>').appendTo(document.body);                       te.attr("url", (this.template.url + "?" + this.template.data));                       $.Tmpl_Data(te, this.data, fun, this.template.cache);                   }               });           }       });   })(jQuery);  复制代码
