我有20条记录
我想按Priority
字段排序记录。Priority
字段具有3个值(High, Medium, Low
)
我想依次显示High, Medium, Low
记录中的记录。
以下是C#
版本--->我需要在javascript中执行此操作
`var groupedRecords = records.OrderByDescending(x => x.Priority == "High").ThenByDescending(x > x.Priority == "Medium").ThenByDescending(x > x.Priority == "Low")`
在Javascript中,
var csvRecords = priorities.split(',');
//现在,我得到混合顺序的csv。我需要按顺序。那就是我想先获取所有高记录,然后获取中记录,最后获取低记录。
最佳答案
您可以看下面的简单代码:
var points = [{Name: "House",Priority :"High"}, {Name: "Travel",Priority :"Medium"}, {Name: "Children",Priority :"High"}, {Name: "Personal Loan",Priority :"Low"}, {Name: "Car",Priority :"Medium"}, {Name: "Shopping",Priority :"Low"}];
document.getElementById("demo").innerHTML = JSON.stringify(points);
function myFunction() {
var priorityArray = ["High", "Medium","Low"]
points.sort(function(a, b){
var firstPrio = priorityArray.indexOf( a.Priority) ;
var secPrio = priorityArray.indexOf(b.Priority)
return firstPrio -secPrio
});
document.getElementById("sortedArray").innerHTML = JSON.stringify(points);
}
<p>Click the button to sort the array.</p>
<button onclick="myFunction()">Sort it</button>
<br/><br/>
Original Array:
<p id="demo"></p>
Sorted Array:
<p id="sortedArray"></p>
希望对您有所帮助。
