我必须得到一个折叠类名称的字符串，并将其带到视图以切换面板。 到目前为止，我设法使用ViewBag.collapse将字符串带到View，但我无法弄清楚如何切换它。 我尝试过像
这样的东西<script>
$("@ViewBag.collapse").collapse("toggle");
</script>
但它不起作用

由于collapse变量引用了CSS类，所以你需要做的只是在类名之前添加句点，所以它呈现像var obj = {};
var qsum_total_sales = 'SELECT SUM (total_price) AS s_total_price FROM myrecords';
var qsum_count_active = 'SELECT COUNT (*) AS s_count_active FROM myrecords WHERE NOT status = "canceled" ';
var qdata = 'SELECT * FROM myrecords';
router.get('/data', function(req, res) {
connection.query(qdata, function(err, result) {
if (err) {
throw err;
} else {
obj = {
print: result
};
console.log(obj);
connection.query(qsum_total_sales, function(err, rows, result1) {
if (err) {
throw err;
} else {
rsum_total_sales = JSON.parse(rows[0].s_total_price).toFixed(2);
console.log(rsum_total_sales);
connection.query(qsum_count_active, function(err, rows2, result2) {
if (err) {
throw err;
} else {
rsum_count_active = JSON.parse(rows2[0].s_count_active);
console.log(rsum_count_active);
//After successful completion of all 3 queries send data back to cliend(front-end)
//its better to create new obj everytime and send it
//store all the data in obj and send back to client
var obj = {};
obj.print = result;
obj.rsum_count_active = rsum_count_active;
obj.rsum_total_sales = rsum_total_sales;
res.render('data', obj);
}
});
}
});
}
});
});
：
.collapse-target现在它正试图找到匹配的HTML元素作为HTML标记，而不是类名。
