我试图生成一个通用的HTML表,其中的列名和内容根据选择而变化。 我原本希望通过id访问数组元素,但是显然它不能正常工作。
这是我的代码:
<% records.forEach(function(record){ %>
<tr role="row" class="odd">
<% for (var i = 0; i < noOfCols; i++) { %>
<td tabindex="0"><%= record[i] %></td>
<% } %>
<td nowrap="">
<span class="dropdown">
<a href="#" class="btn m-btn m-btn--hover-brand m-btn--icon m-btn--icon-only m-btn--pill" data-toggle="dropdown" aria-expanded="true">
<i class="la la-ellipsis-h"></i>
</a>
<div class="dropdown-menu dropdown-menu-right">
<a class="dropdown-item" href="#"><i class="la la-edit"></i> Edit Details</a>
<a class="dropdown-item" href="#"><i class="la la-leaf"></i> Update Status</a>
<a class="dropdown-item" href="#"><i class="la la-print"></i> Generate Report</a>
</div>
</span>
<a href="#" class="m-portlet__nav-link btn m-btn m-btn--hover-brand m-btn--icon m-btn--icon-only m-btn--pill" title="View">
<i class="la la-edit"></i>
</a>
</td>
</tr> <% }); %>
<%= record[i] %>
不幸返回null
。
这是我的app.js代码块,可路由到页面:
app.get('/edit/:tblId', async function(req, res, next) {
console.log("***************** Edit Table *******************");
const allDatabases = await dbInstance.genericQuery(dbQueries.allDbSQL);
const allTables = await dbInstance.genericQuery(dbQueries.allTbSQL);
const singletable = await dbInstance.genericQuery(dbQueries.singleTableSQL.replace('{tblId}', req.params.tblId));
const tableName = await dbInstance.getTableName(req.params.tblId);
const columnNames = await dbInstance.genericQuery(dbQueries.headersTbSQL.replace('{tblId}', req.params.tblId));
const records = await dbInstance.getTableRecords(tableName);
const noOfCols = await dbInstance.genericQuery(dbQueries.headersTbSQL.replace('col.column_name', 'count(1) colNo').replace('{tblId}', req.params.tblId));
console.log('SQL: ' + dbQueries.headersTbSQL.replace('col.column_name', 'count(1) colNo').replace('{tblId}', req.params.tblId))
console.log('noOfCols: ' + noOfCols[0].colNo);
console.log(records);
res.render('edit_table_new', {
parameters: arrayOpsInstance.getMatchDBWithTables(allDatabases, allTables),
tblName: tableName,
pagePathDatabase: 'EDIT DATA - ' + singletable[0].database_name.toUpperCase(),
pagePathSchema: singletable[0].schema_name.toUpperCase(),
tableDesc: singletable[0].table_desc,
headers: columnNames,
records: records,
noOfCols: Number(noOfCols[0].colNo)
});
});
这是记录数组:
[ RowDataPacket {
database_id: 1,
database_name: 'REFERA',
organization_id: 1,
database_type_id: 3,
database_alias: 'Refera Repository',
database_desc: 'Holds Refera Repository Information',
ip_number: 'localhost',
port_number: '3306',
service_name: 'refera',
username: 'uuu',
password: 'ppp' },
RowDataPacket { database_id:2 database_name:“ MAKEIT表”, Organization_id:1 database_type_id:1, database_alias:“ MAKEIT临时表”, database_desc:'保留MAKEIT临时表', ip_number:'本地主机', port_number:'1521', service_name:“ XE”, 用户名:'uuu', 密码:'ppp'}]
如果您能提供帮助,我非常感谢(我正在使用NodeJS,并且更喜欢在HTML文件中生成HTML短语,而不是在脚本中进行计算。)
答案 0 :(得分:1)
records
数组中的项目本身不是数组(RowDataPacket
)。它们是对象,因此您不能像以前那样通过这种for loop
遍历它们。
您可以使用
for(let prop in obj){
//access values with obj[prop]
}
