目前我希望在模板中有一个可点击的锚标记来显示一条消息。但是，在运行期间，我一直收到此错误。
未捕获的ReferenceError：未定义显示
我的代码如下：
prepareKendoGrid(searchresults:any[]) {
console.log(this.searchresults);
this.adhocSearchKendoGrid = {
sortable: true,
columns: [{
field: "filename",
title: " ",
width: 50,
template: "#if(filetype == 'xml') {#<i style='margin-left:10px' class='fa fa-file-code-o fa-1x'></i>#} else if(filetype == 'doc') {#<i style='margin-left:10px' class='fa fa-file-word-o fa-1x'></i>#} else if(filetype == 'pdf') {#<i style='margin-left:10px' class='fa fa-file-pdf-o fa-1x'></i>#}else if(filetype == 'txt') {#<i style='margin-left:10px' class='fa fa-file-text-o fa-1x'></i>#}#"
},
{
field: "filename",
title: "File Name",
width: 200
},
{
field: "content",
title: "Content"
},
{
field: "start_time",
title: "Conversation Date",
width: 200
},
{
field: "attachments.count",
title: "Attachments",
width: 100,
template: "<a style='margin-right:10px' (click)='display()'><i class='fa fa-paperclip fa-fw'></i></a>#: attachments.count #"
}],
dataSource: searchresults
};
let cst = new CSTGridComponent();
cst.createGrid(this.adhocSearchKendoGridId,this.adhocSearchKendoGrid);
}
display() {
console.log('ok');
}
}
