angular has its own life cycle. When looping to a variable monitored by angular. It is best to use the loop method that comes with Angular. "angular.foreach"

Format:

Copy code The code is as follows:

var objs =[{a:1},{a:2}];

angular.forEach(objs, function(data,index,array){

//data is equivalent to array[index]

console.log(data.a '=' array[index].a);

});

The parameters are as follows:

objs: Collection that needs to be traversed

data: current data during traversal

index: current index when traversing

array: The collection that needs to be traversed, objs will be passed as it is every time it is traversed.

Copy code The code is as follows:

var objs =[{a:1},{a:2}];

angular.forEach(objs, function(data){
