问题描述
这是到我的小提琴
我有一个从Ajax响应中获得的JSON动态创建的表。
表中有重复的条目。例如 xxx,xxx
。
我想对它们进行分组,并使它像< td data-count =some count> xxx< / td>
我尝试使用 underscore.js
,但它似乎打破了 rowspan
功能。
我使用 _countBy(arr)$ c>将
arr
$ c $>,并且我获得了以下格式的对象。
{xxx:2,zzz:1}
问题:如何修改 generateTable()
函数以适应此更改。我尝试按以下方式修改它:
var i = 0;
$ .each(queryObject,function(key,value){
if(i == 0){
i ++;
childrenHtml + =('< td rowspan =1data-count =''+ value +'>'+ key +'< / td>'+'< / tr>');
}
else {
childrenHtml + =('< tr>< td rowspan =1data-count =''+ value +'>'+ key +'< / td>'+'< / tr> ;');
}
});
但是rowspan似乎是现在的问题。我如何修改这个?
您需要像这样做功能来转换您的数据并对其进行分组:
_.chain(data.result)
.keys()//获取所有键buildname1 buildname2..etc
.flatten()
.each(function(key){//为每个键做一次映射并返回一个分组
data.result [key] = _.chain(data.result [ map(function(d){
var key = _.chain(d).keys()。first()。value();
var ob = {} ;
ob [key] = _.chain(d).values()。flatten()。groupBy()。value(); //按值分组
return ob;
} ).value();
}).value();
这会将您的数据集转换为以下格式:
{
buildname1:[
{
table1:{
xxx:[
xxx
],
zzz:[
zzz,
zzz
]
}
},
{
table2:{
xxx:[
xxx
],
yyy:[
yyy
}
}
],
buildname2:[
{
table1:{
xxx:[
xxx,
xxx
],
zzz:[
zzz
]
}
b
$ xxx $ b $ xxx
$ xxx
$
}
},
{
table3:{
xxx:[
xxx
],
yyy: [
yyy
]
}
}
]
}
然后,您需要更改用于制作表格和计算rowspan的biz逻辑。
工作代码
Here is a link to my Fiddle
I have a table that is created dynamically from the JSON obtained from a Ajax response.
I have duplicate entries in the table. For example xxx,xxx
.I want to group them and have it like <td data-count="some count">xxx</td>
I tried using underscore.js
but it seems to break the rowspan
functionality.
I converted the arr
into a object using _countBy(arr)
and I obtained an object of the following format.
{xxx: 2, zzz: 1}
Question : How can I modify the generateTable()
function to accommodate this change. I tried to modify it the following way
var i=0;
$.each(queryObject,function(key,value){
if(i == 0){
i++;
childrenHtml += ('<td rowspan="1" data-count="'+value+'">' + key + '</td>' + '</tr>');
}
else{
childrenHtml += ('<tr><td rowspan="1" data-count="'+value+'">' + key + '</td>' + '</tr>');
}
});
But the rowspan seems to be problem now. How can I modify this?
You will need to make function like this to convert your data and group it:
_.chain(data.result)
.keys()//get all the keys buildname1 buildname2..etc
.flatten()
.each(function(key) {//for each key do a mapping and return a grouping.
data.result[key] = _.chain(data.result[key]).flatten().map(function(d) {
var key = _.chain(d).keys().first().value();
var ob = {};
ob[key] = _.chain(d).values().flatten().groupBy().value();//grouping by value
return ob;
}).value();
}).value();
This will convert your data set into this format:
{
"buildname1":[
{
"table1":{
"xxx":[
"xxx"
],
"zzz":[
"zzz",
"zzz"
]
}
},
{
"table2":{
"xxx":[
"xxx"
],
"yyy":[
"yyy"
]
}
}
],
"buildname2":[
{
"table1":{
"xxx":[
"xxx",
"xxx"
],
"zzz":[
"zzz"
]
}
},
{
"table2":{
"xxx":[
"xxx",
"xxx"
]
}
},
{
"table3":{
"xxx":[
"xxx"
],
"yyy":[
"yyy"
]
}
}
]
}
Then you will need to change the biz logic for making table, and calculating rowspan.
