ExtJS Grid Tooltip提示本文总结了ExtJS Grid Tooltip的几种实现方法。ExtJS Grid Tooltip可以通过表头提示

ExtJS Grid Tooltip提示

ExtJS Grid Tooltip实现之一：表头提示

在2.2里面是设置ColumnModel.tooltip ,3.0则是Column. tooltip 如下:

var?grid?=?new?Ext.grid.GridPanel({?? ???columns:[?? ?
????{header:'名称',dataIndex:'name',tooltip:'对象名称'},?? ?????{header:'开始时间?-?结束时间?<?br/>成功/失败/成功率',?dataIndex:'sucRate',tooltip:'成功/失败/成功率'}?? ?
??]?? ?});??

ExtJS Grid Tooltip实现之二：单元格提示

1)使用Ext.QuickTips

在开始的时候就执行Ext.QuickTips.init();

然后对需要提示的单元格,重写renderer函数,添加ext:qtitle , ext:qtip这2个属性即可。

这个在官方的FAQ上有详细描述: http://extjs.com/learn/Ext_FAQ_Grid#Add_ToolTip_or_Qtip

//option?1?? ? //========?? ?

renderer?=?function?(data,?metadata,?record,?rowIndex,?columnIndex,?store)?{?? ?

????var?title?=?'Details?for?'?+?value?+?'-'?+?record.get('month')?+?? ? ????????'-'?+?record.get('year');?? ?
????var?tip?=?record.get('sunday_events');?? ? ??? ?
????metadata.attr?=?'ext:qtitle="'?+?title?+?'"'?+?'?ext:qtip="'?+?tip?+?'"';?? ? ??? ?
????//return?the?display?text:?? ? ????var?displayText?=?'<?span?style="color:?#000;">'?+?value?+?'<?/span><?br?/>'?+?? ?
????????record.get('sunday_events_short');?? ? ????return?displayText;?? ?
};?? ? ??? ?
//option?2?? ? //========?? ?
renderer?=?function?(data,?metadata,?record,?rowIndex,?columnIndex,?store)?{?? ? ????var?qtip?=?'>';?? ?
????if(data?>=?0){?? ? ????????qtip?=?"?qtip='yeah'/>";?? ?
????????return?'<?span?style="color:green;"'?+?qtip?+?data?+?'%<?/span>';?? ? ????}else?if(data?<??0){?? ?
????????qtip?=?"?qtip='woops'/>";?? ? ????????return?'<?span?style="color:red;"'?+?qtip?+?data?+?'%<?/span>';?? ?
????}?? ? ????return?data;?? ?
};?? ? ??? ?
//option?3?? ? //========?? ?
var?qtipTpl?=?new?Ext.XTemplate(?? ? ????'<?h3>Phones:<?/h3>',?? ?
????'<?tpl?for=".">',?? ? ????'<?div><?i>{phoneType}:<?/i>?{phoneNumber}<?/div>',?? ?
????'<?/tpl>'?? ? );?? ?
??? ? renderer?=?function?(data,?metadata,?record,?rowIndex,?columnIndex,?store)?{?? ?
??? ? ????//?get?data??? ?
????var?data?=?record.data;?? ? ??? ?
????//?convert?phones?to?array?(only?once)??? ? ????data.phones?=?Ext.isArray(data.phones)???? ?
????????data.phones?:??? ? ????????this.getPhones(data.phones);?? ?
??? ? ????//?create?tooltip??? ?
????var?qtip?=?qtipTpl.apply(data.phones);?? ? ??? ?
????metadata.attr?=?'ext:qtitle="'?+?title?+?'"'?+?'?ext:qtip="'?+?tip?+?'"';?? ? ??? ?
????//return?the?display?text:?? ? ????return?data;?????? ?
};???

2)使用ToolTip

官方也已经给出方法:

http://extjs.com/forum/showthread.php?t=55690

以上给出的方法是可以让一个grid里面的元素共享一个tooltip对象。一般用来做rowtip

不过3.0有更好的方式,如下:

ExtJS Grid Tooltip实现之三：行提示 RowTip

ExtJS3.0新增的方法,设置tooltip的delegate

var?myGrid?=?new?Ext.grid.gridPanel(gridConfig);?? ? myGrid.on('render',?function(grid)?{?? ?
????var?store?=?grid.getStore();??//?Capture?the?Store.?? ? ?? ?

????var?view?=?grid.getView();????//?Capture?the?GridView.?? ?

????myGrid.tip?=?new?Ext.ToolTip({?? ? ????????target:?view.mainBody,????//?The?overall?target?element.?? ?
?? ? ????????delegate:?'.x-grid3-row',?//?Each?grid?row?causes?its?own?seperate?show?and?hide.?? ?
?? ? ????????trackMouse:?true,?????????//?Moving?within?the?row?should?not?hide?the?tip.?? ?
?? ? ????????renderTo:?document.body,??//?Render?immediately?so?that?tip.body?can?be?referenced?prior?to?the?first?show.?? ?
?? ? ????????listeners:?{??????????????//?Change?content?dynamically?depending?on?which?element?triggered?the?show.?? ?
?? ? ????????????beforeshow:?function?updateTipBody(tip)?{?? ?
?????????????????? var rowIndex = view.findRowIndex(tip.triggerElement);
?
??????????????????? if(!Ext.isEmpty(content)){
?? ??????????????? ??? ?tip.body.dom.innerHTML = "提示信息";
?? ???????????????? }else{
?? ??????????????? ??? ?return false; //停止执行，从而禁止显示Tip
?? ??????????????? ??? ?tip.destroy();
?? ???????????????? }
????????????}?? ? ????????}?? ?
????});?? ? });???
