扩展eXtremeTable 行事件,增加js事件属性

扩展eXtremeTable 行事件：

修改eXtremeTable 源码增加双击事件：

1.       修改extremecomponents.tld 文件找到Row Tag 增加属性ondblclick

 

<attribute>          <name>ondblclick</name>          <required>false</required>          <rtexprvalue>true</rtexprvalue>              <description><![CDATA[The javascript ondblclick action -add by lovejj]]></description>         </attribute>

 

2.       Row.java 文件增加ondblclick属性，并生成相应的get，set方法

 

private String ondblclick;//add by lovejj

 

3.       HtmlBuilder.java 增加ondblclick 方法：

 

/**      * @author loveJJ      * <p>The ondblclick attribute [ondblclick=].</p>      */     public HtmlBuilder ondblclick(String ondblclick) {     if (StringUtils.isNotBlank(ondblclick)) {         write(" ondblclick=\"").write(ondblclick).write("\" ");     }         return this;     }

 

4.       RowBuilder.java 增加ondblclick方法：

 

public void ondblclick() {//add by lovejj         String ondblclick = row.getOndblclick();         html.ondblclick(ondblclick);     }

并修改该类中的    rowStart() 方法为：

public void rowStart() {         html.tr(1);         styleClass();         style();         onclick();         onmouseover();         onmouseout();         ondblclick();//默认是没有这一行的 add by loveJJ         html.close();     }

 

5.       修改RowTag.java 文件：

 

现在就进入到了关键的一步中，在Tag标签类中让其展现出来，首先增加属性

private String ondblclick;//add by lovejj

然后生成该属性的set方法

public void setOndblclick(String ondblclick) {        this.ondblclick = ondblclick;     }

 

并修改doStartTag()方法：

在else方法中增加一行:

row.setOndblclick(TagUtils.evaluateExpressionAsString("ondblclick", ondblclick, this, pageContext));//add by lovejj

 

例如本人修改的doStartTag方法最后为:

public int doStartTag() throws JspException {         try {             TableModel model = TagUtils.getModel(this);               if (TagUtils.isIteratingBody(this)) {                 Row row = model.getRowHandler().getRow();                 row.setOnclick(TagUtils.evaluateExpressionAsString("onclick", onclick, this, pageContext));                 row.setOnmouseout(TagUtils.evaluateExpressionAsString("onmouseout", onmouseout, this, pageContext));                 row.setOnmouseover(TagUtils.evaluateExpressionAsString("onmouseover", onmouseover, this, pageContext));                                 modifyRowAttributes(model, row);                 model.getRowHandler().modifyRowAttributes();             } else {                 Row row = new Row(model);                 row.setHighlightClass(TagUtils.evaluateExpressionAsString("highlightClass", this.highlightClass, this, pageContext));                 row.setHighlightRow(TagUtils.evaluateExpressionAsBoolean("highlightRow", this.highlightRow, this, pageContext));                 row.setInterceptor(TagUtils.evaluateExpressionAsString("interceptor", this.interceptor, this, pageContext));                 row.setOnclick(TagUtils.evaluateExpressionAsString("onclick", onclick, this, pageContext));                 row.setOnmouseout(TagUtils.evaluateExpressionAsString("onmouseout", onmouseout, this, pageContext));                 row.setOnmouseover(TagUtils.evaluateExpressionAsString("onmouseover", onmouseover, this, pageContext));                 row.setStyle(TagUtils.evaluateExpressionAsString("style", style, this, pageContext));                 row.setStyleClass(TagUtils.evaluateExpressionAsString("styleClass", styleClass, this, pageContext));                 row.setOndblclick(TagUtils.evaluateExpressionAsString("ondblclick", ondblclick, this, pageContext));//add by lovejj                   addRowAttributes(model, row);                 model.addRow(row);             }         } catch (Exception e) {             throw new JspException("RowTag.doStartTag() Problem: " + ExceptionUtils.formatStackTrace(e));         }                 return EVAL_BODY_INCLUDE;     }

 

OK到此修改完毕,

Test.jsp中即可加入

<ec:row ondblclick="alert('sd');">

进行测试了.
