ExtJS Grid Tooltip提示 鼠标悬停

Posted 2023-01-10

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，单元格提示，行提示以及自己手动添加等方式完成。本文参考了官方FAQ上提供的描述。
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)

//build the qtip:    
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:

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();
                

            
        
);

);
