我目前正在做一个项目,我需要将一些旧代码转换为 json 对象。我们从 sql 查询中获取结果集,并将它返回的类别作为 json 返回。我不太精通javascript,更不用说json了,所以我不确定最简单的方法是什么。这是我需要更改为 JSON 的函数:
function createOutputCategories(){
try
{
output =
"<html>" +
"<head>" +
"<title>" +
"You can find it!" +
"</title>" +
"</head>" +
"<body bgcolor='#CED3F3'>" +
"<a href='" + url + "file.xsjs?parent=1'>" +
"</a>" +
"<br><br>";
if(parent === "1"){
output = output + "<h3><font color='#AAAAAA'>Home</font>";
}else{
output = output +"<a href='javascript:history.back()'>" +
"<h3>Back";
}
output = output +
"</h3>" +
"</a>" +
"<h1>" +
"Categories:" +
"</h1>";
while(rs.next()){
if(rs.getString(3) === 0 || rs.getString(3) === null || rs.getString(3) === undefined || rs.getString(3) === "0" ){
output = output + "<br><a href='" + url + "yeti.xsjs?parent=" + rs.getString(1) + "'>" + rs.getString(2) + "</a>";
}else{
output = output + "<br><a href='" + url + "yeti.xsjs?parent=" + rs.getString(1) + "'>" + rs.getString(3) + "</a>";
}
}
}catch(Exception){
$.response.contentType = "text/plain";
$.response.setBody( "Failed to retreive data" );
$.response.status = $.net.http.INTERNAL_SERVER_ERROR;
}
这是我到目前为止所拥有的,但我没有返回有效的 JSON 对象:
function createOutputCategories(){
try{
output =
"category: {name = \"" + parent + "\"; description = \"\"}";
output = output +
"subcategories: [ ";
while(rs.next()){
output = output +
"{ catid = \"" + rs.getString(1) + "\"; catname = \"" + rs.getString(2) + "\"; altname = \"" + rs.getString(3) + "\"; description = \"" + rs.getString(4) + "\"}";
}
output = output +
"];";
}
catch(Exception){
$.response.contentType = "text/plain";
$.response.setBody( "Failed to retreive data" );
$.response.status = $.net.http.INTERNAL_SERVER_ERROR;
}
如果我需要提供其他任何东西,请告诉我!谢谢!
