在上一篇JQuery模板插件-jquery.tmpl中介紹了這款插件。有時我們需要去動態的ajax去加載模板,或者數據,根據url參數或者其他信息加載不同的模板,數據。在我的某個項目中有這個需求,所以特地寫成jquery工具函數,加入了本地數據和ajax數據加載模板,數據的方式。
參數說明:
Tmpl: function(template, data, fun)
1:template:
1): url: 為ajax的加載url,ajax當且僅當remote= true時候加載。
2):data: 為ajax加載參數
3) templateSelector: 為本地模板選擇器,當且僅當remote= false時使用
4) remote: true為ajax,false為本地數據,
5) cache: 指示是否對模板緩存。
2:data:
1): url: 為ajax的加載url,ajax當且僅當remote= true時候加載。
2):data: 為ajax加載參數
3) templateData: 為本地數據,當且僅當remote= false時使用
4) remote: true為ajax,false為本地數據,
5) cache: 指示是否對模板緩存。
3:fun為回調函數:
fun(jquery.tmpl對象,模板script,數據);
具體代碼如下:
. 代碼如下:
; (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);

後台ajax數據:
. 代碼如下:
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"":""學生{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();
}
}
