我是初学者。
我正在尝试在我的href标签中动态添加id,但它无效。
这是我的代码。
<div class="col-md-6" v-for="Product in data">
<div class="panel panel-default" >
<div class="panel-heading">
{{ Product.name }}
</div>
<div class="panel-body" v-for = "Category in Product.Categories">
<div class="panel-group" id="accordion">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<!--SEE HREF BELOW -->
<a data-toggle="collapse" data-parent="#accordion" href="#{{Category._id}}" >
{{ Category.name }}</a>
</h4>
</div>
<!-- SEE ID BELOW AS WELL -->
<div id="{{ Category._id }}" class="panel-collapse collapse">
<div class="panel-body"></div>
</div>
</div>
</div>
</div>
</div>
我正在尝试将_id提供给<a data-toggle="collapse" data-parent="#accordion" href="#{{Category._id}}">
中的href,并且在href中,我在上面的href上给出<div id="{{ Category._id }}" class="panel-collapse collapse">
标记的ID。
我该怎么做?

试试这个:
:href="`#${Category._id}`"
冒号告诉Vue将值解释为JavaScript,而不是字符串。 反引号正在进行字符串插值,因此您可以使用前面的哈希值。

您无法在第2阶段使用插值,您需要将属性绑定到某个数据对象或使用v-bind(或冒号速记)计算:
cfspreadsheet
我会使用computed:
<cfset objSpreadsheet = SpreadsheetNew()>
<!--- Create and format the header row. --->
<cfset SpreadsheetAddRow( objSpreadsheet, "Location,Percent of Total Checklists,Location Total" )>
<cfset SpreadsheetFormatRow( objSpreadsheet, {bold=true, alignment="center"}, 1 )>
<!--- Populate the spreadsheet. --->
<cfset SpreadsheetSetCellValue( objSpreadsheet, 'FSC', 2, 1, "String" ) >
<cfset SpreadsheetSetCellValue( objSpreadsheet, .03, 2, 2, "Numeric" ) >
<cfset SpreadsheetSetCellValue( objSpreadsheet, 13, 2, 3, "Numeric" ) >
<cfset SpreadsheetSetCellValue( objSpreadsheet, 'OPERATIONS', 3, 1, "String" ) >
<cfset SpreadsheetSetCellValue( objSpreadsheet, 13.78, 3, 2, "Numeric" ) >
<cfset SpreadsheetSetCellValue( objSpreadsheet, 5161, 3, 3, "Numeric" ) >
<cfheader name="Content-Disposition" value="attachment; filename=LS_#Dateformat(NOW(),'MMDDYYYY')#">
<cfcontent type="application/vnd.ms-excel" variable="#SpreadsheetReadBinary( objSpreadsheet )#">
然后你会这样做:
<a data-toggle="collapse" data-parent="#accordion" href="#{{Category._id}}" >
这是一个向您展示的JSFiddle:https://jsfiddle.net/ym29dd2n/
有关:
new Vue({
el: '#app',
computed:{
href(){
return '#' + this.Category._id
}
},
data(){
return {
Category: {
_id: 1
}
}
}
})
它是相同的,但你可以直接绑定id:
<a data-toggle="collapse" data-parent="#accordion" v-bind:href="href">
