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

后台ajax数据:
View Code protected void Page_Load(object sender, EventArgs e) { if (Request["ajax"] == "1") { Response.Clear(); Response.ContentType = "application/json"; System.Text.StringBuilder sb = new System.Text.StringBuilder("["); for (int i = 0; i < 20; i++) { sb.AppendFormat(@" {{ ""Name"":""学生{0}"", ""Sex"":""{1}"", ""ID"": {0}, ""Class"": [ {{ ""ClassName"":""Class{0}"", ""Count"": {2} }}, {{ ""ClassName"":""Class2{0}"", "" Count"": {3} }} ] }},", i, i % 2 == 0 ? "男" : "女", (i + 10) / 2, (i + 20) / 2); } sb.Remove(sb.Length - 1, 1); sb.Append("]"); Response.Write(sb.ToString()); Response.Flush(); Response.Close(); Response.End(); } } 复制代码
