How to add a picture state or button to Extjs grid_extjs

We often need to add a picture status or button in the extjs grid. Let’s summarize the methods we have used:

1. Status representation:

Copy code The code is as follows:

renderer:function(value){
if(value==0){
return "";
}else if(value==1){
return "";
}
return value;
}

Add renderer identification status in columns. The effect is as follows:

2. Event handling:

Add onclick event directly to img:

Copy the code The code is as follows:

'

The event is to pass the required data.

Another way is to add a cell click event to the grid:

Copy the code The code is as follows:

listeners: {
cellClick: viewDoc
}

function viewDoc(grid, rowIdx, colIdx, e) {
var action = e.getTarget(). value;

}

In this way, you can get the clicked cell and then add event processing.

3. You can use 'actioncolumn' to add image buttons

Copy code The code is as follows:

{header:'certificate',sortable:false,width:80,align:'center',scope:this,

xtype:

'actioncolumn',
items : [{
icon : '${ctx}/img/details.png',
tooltip : 'Display certificate',
handler : function(grid, rowIndex, colIndex) {
var record = grid.getStore().getAt(rowIndex);
//. . .
}
]}

This way you can also add pictures to grid cells.
