问题描述
我 JSON数据

说明
应空
,但所有的值转移到左。或
如果所有的值都是空的任何属性隐藏特定列
块引用>解决方案为了确定列是否为空,你需要一些列的配置,获取通过遍历数据,看看是否所有行包含数据的创建标题(对象键)。
然后你可以使用该列配置阵列作为中继器的
百分位>
和< TD>
。举例配置:
[
{
标题:ID,
显示:真
},
{
标题:标题,
显示:真
},
{
标题:说明,
显示:真
},
{
标题:测试,
显示:假的
}

VAR键= Object.keys(数据[0]); 功能createConfig(){
变种validKeyCounts = {};
VAR colConfig;
keys.forEach(功能(键){
validKeyCounts [关键] = 0;
})
data.forEach(函数(行,IDX){
keys.forEach(功能(键){
如果(row.hasOwnProperty(键)及和放大器;!行[关键] == NULL){
validKeyCounts [关键] ++;
}
})
}); colConfig = keys.map(功能(键){
返回{
标题:键,
显示:validKeyCounts [关键]> 0
}
});
返回colConfig }我敢肯定,这可以优化,但仅仅是开始使用功能的方式想

I'm
binding json data
tong-table
usingangular js
if any value is null then positions for all columns gets disturb can any one help me to fix data with column header ?
see this plunker http://plnkr.co/edit/Ixvp8B0dRwOBDHflmu2j?p=preview
Description
should benull
but all values shifted to left.Or If all values are null for any property hide that particular column
解决方案In order to determine if a column is empty you need some sort of column configuration that gets created by iterating the data to see if all rows contain data for any of the headings (object keys).
Then you can use that column configuration array as the repeater for the
<th>
and<td>
.Example config:
[ { "heading": "Id", "display": true }, { "heading": "Title", "display": true }, { "heading": "Description", "display": true }, { "heading": "Test", "display": false } ]
HTML
<thead> <tr> <th ng-repeat="col in colConfig" ng-if="col.display">{{col.heading}}</th> </tr> </thead> <tbody> <tr ng-repeat="item in data"> <td ng-repeat="col in colConfig" ng-if="col.display"> {{item[col.heading]}} </td> </tr> </tbody>
Example config create
var keys = Object.keys(data[0]); function createConfig() { var validKeyCounts = {}; var colConfig; keys.forEach(function (key) { validKeyCounts[key] = 0; }) data.forEach(function (row, idx) { keys.forEach(function (key) { if (row.hasOwnProperty(key) && row[key] !== null) { validKeyCounts[key]++; } }) }); colConfig = keys.map(function (key) { return { heading: key, display: validKeyCounts[key] > 0 } }); return colConfig }
I'm sure this could be optimized but is just a way to get started with functionality wanted
