在Asp.net中使用JQuery插件之jTip

     jTip 是个轻量级的提示插件。默认支持两个参数：

• 　　width宽度，default value :250px
•       link 要link的URL

　对应的Source code是:

1: var params = parseQuery( queryString ); 2: if(params['width'] === undefined){params['width'] = 250}; 3: if(params['link'] !== undefined){ 4: $('#' + linkId).bind('click',function(){window.location = params['link']}); 5: $('#' + linkId).css('cursor','pointer'); 6: }

　

然后我们看到初始化时，是选择所有class=jTip的<a>标签，然后给它们加上hover方法，让click方法失效

1: //on page load (as soon as its ready) call JT_init 2: $(document).ready(JT_init); 3:   4: function JT_init(){ 5: $("a.jTip") 6: .hover(function(){JT_show(this.href,this.id,this.name)},function(){$('#JT').remove()}) 7: .click(function(){return false}); 8: }

接着取得当前id的位置计算将要显示DIV的位置，code也不复杂：

1: if(hasArea>((params['width']*1)+75)){ 2: $("body").append("<div id='JT' style='width:"+params['width']*1+"px'><div id='JT_arrow_left'></div><div id='JT_close_left'>"+title+"</div><div id='JT_copy'><div class='JT_loader'><div></div></div>");//right side 3: var arrowOffset = getElementWidth(linkId) + 11; 4: var clickElementx = getAbsoluteLeft(linkId) + arrowOffset; //set x position 5: }else{ 6: $("body").append("<div id='JT' style='width:"+params['width']*1+"px'><div id='JT_arrow_right' style='left:"+((params['width']*1)+1)+"px'></div><div id='JT_close_right'>"+title+"</div><div id='JT_copy'><div class='JT_loader'><div></div></div>");//left side 7: var clickElementx = getAbsoluteLeft(linkId) - ((params['width']*1) + 15); //set x position 8: } 9: 10: $('#JT').css({left: clickElementx+"px", top: clickElementy+"px"}); 11: $('#JT').show(); 12: $('#JT_copy').load(url);

 

其它的一些help function可以参看source code，你可以从这里下载它.

如何使用呢？我们引入它与相应的CSS：

1: <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jQuery/jquery-1.3.2.min.js"></script> 2: <script src="js/jtip.js" type="text/javascript"></script>

在asp.net webform中使用Handler,asp.net mvc 可以用action.这个用Handler演示：

1: [WebService(Namespace = "http://tempuri.org/")] 2: [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 3: public class DataHandler : IHttpHandler 4: { 5: #region Properties (1) 6:   7: public bool IsReusable 8: { 9: get 10: { 11: return false; 12: } 13: } 14:   15: #endregion Properties 16:   17: #region Methods (2) 18:   19: // Public Methods (1) 20:   21: public void ProcessRequest(HttpContext context) 22: { 23: context.Response.ContentType = "text/plain"; 24: context.Response.Write(GetData(Convert.ToInt32(context.Request.QueryString["id"]))); 25: } 26: // Private Methods (1) 27:   28: private string GetData(int key) 29: { 30: Dictionary<int, string> mydatadic = new Dictionary<int, string>(); 31: mydatadic.Add(0, "Nothing in life is to be feared. It is only to be understood,this is id equal 0"); 32: mydatadic.Add(1, "<strong>A man</strong> is not old as long as he is seeking something. A man is not old until regrets take the place of dreams. ,this is id equal 1"); 33: mydatadic.Add(2, "A man can succeed at almost anything for which he has unlimited enthusiasm.,this is id equal 2"); 34: mydatadic.Add(3, "To live is to function. That is all there is in living. ,this is id equal 3"); 35: return mydatadic[key]; 36: } 37:   38: #endregion Methods 39: }

 

好的，在最终的HTML中这么写：

1: <span class="formInfo"><a href="DataHandler.ashx?id=0&width=375" class="jTip" id="one" name="Password must follow these rules:">?</a></span> 2: <br> 3:   4: <p><a href="DataHandler.ashx?id=3&width=175&amp;link=http://www.google.com" name="Before You Click..." id="googleCopy" class="jTip">Go To Google</a></p> 5:   6: <a href="DataHandler.ashx?id=3" class="jTip" id="three">Tip No Caption</a>

默认是取name attribute value为Caption，上面是三种典型的link。id是我们自己传给Handler的QueryString,最终效果如下图所示：
