[英]How can I add a header to my JSON output table?
我正在尝试向此JSON输出表添加标头,但我不知道如何执行此操作。 这段代码为我提供了一个表格,该表格中填充了从数据库返回的数据,并将其置于由<td><tr>
标记构成的表格格式中。 问题是我需要一个表头,而且我不知道该如何编码该零件。 有任何想法吗?
function renderSearchResults( results, domNode ) {
var i;
var out = "<table>";
if (results.length === 0) {
domNode.innerHTML = 'No results matching your search.';
return;
}
// loop to print the JSON in a table format
results.forEach(function (result) {
console.info(result);
out += "<tr><td>" +
result.ContractId +
"</td><td>" +
result.ContractTitle +
"</td><td>" +
result.Terminal +
"</td><td>" +
result.Cabinet +
"</td><td>" +
result.Section +
"</td><td>" +
result.Folder +
"</td><td>" +
result.Sheet +
"</td><td>" +
result.Consult +
"</td><td>" +
result.Location +
"</td><td>" +
result.Active +
"</td><td>" +
result.Theme +
"</td><td>" +
result.Construction +
"</td><td>" +
result.Subtheme +
"</td><td>" +
result.AsBuilt +
"</td><td>" +
result.Year +
"</td><td>" +
"<a href= " + result.Path + " target=_blank>" + "Binder" + "</a>"
} );
out += "</table>";
domNode.innerHTML = out;
}
在最初声明out
,可以放入<th>
或tableheader标记,即:
function renderSearchResults( results, domNode ) {
var i;
var out = "<table><th>ContractId</th><th>ContractTitle</th><th>Terminal</th><th>Cabinet </th><th>Section </th><th>Folder </th><th>Sheet </th><th>Consult </th><th>Location </th><th>Active </th><th>Theme </th><th>Construction </th><th>Subtheme </th><th>AsBuilt </th><th>Year </th>";
if (results.length === 0) {
domNode.innerHTML = 'No results matching your search.';
return;
}
results.forEach(function (result) {
console.info(result);
out += "<tr><td>" +
(result.ContractId !== null ? result.ContractId : 'Not Applicable') +
"</td><td>" +
(result.ContractTitle !== null ? result.ContractTitle : 'Not Applicable') +
"</td><td>" +
(result.Terminal !== null ? result.Terminal : 'Not Applicable') +
"</td><td>" +
(result.Cabinet !== null ? result.Cabinet : 'Not Applicable') +
"</td><td>" +
(result.Section !== null ? result.Section : 'Not Applicable') +
"</td><td>" +
(result.Folder !== null ? result.Folder : 'Not Applicable') +
"</td><td>" +
(result.Sheet !== null ? result.Sheet : 'Not Applicable') +
"</td><td>" +
(result.Consult !== null ? result.Consult : 'Not Applicable') +
"</td><td>" +
(result.Location !== null ? result.Location : 'Not Applicable') +
"</td><td>" +
(result.Active !== null ? result.Active : 'Not Applicable') +
"</td><td>" +
(result.Theme !== null ? result.Theme : 'Not Applicable') +
"</td><td>" +
(result.Construction !== null ? result.Construction : 'Not Applicable') +
"</td><td>" +
(result.Subtheme !== null ? result.Subtheme : 'Not Applicable') +
"</td><td>" +
(result.AsBuilt !== null ? result.AsBuilt: 'Not Applicable') +
"</td><td>" +
(result.Year !== null ? result.Year : 'Not Applicable')+
"</td><td>" +
"<a href= " + result.Path + " target=_blank>" + "Binder" + "</a>"
} );
out += "</table>";
console.log(out);
domNode.innerHTML = out;
}
表头有一个不同的标记。
<tr>
用于标题的<th>
行,数据用于<td>
。
您可以在此处查看更多信息。
您可以在检查结果后添加标题:
if (results.length === 0) {
domNode.innerHTML = 'No results matching your search.';
return;
} else {
out += "<tr><th>Header</th></tr>"
}
