你好，我尝试从表中删除行，前两行背景为红色，另一行背景为白色。
如果我尝试删除最后一行， 它将被删除，但颜色将仅用于第一行(它应该用于第一行和第二行)
下面 plnkr 中的示例:尝试通过在 coulmn University 中单击 x 来删除最后一行:

脚本.js:
// Code goes here
var table = function($scope)
{
$scope.students=[
{Rollno: "1122",Name: "abc",Uni: "res",color:"red"},
{Rollno: "2233",Name: "def",Uni: "tuv",color:"red"},
{Rollno: "23432",Name: "g325325hi",Uni: "wxy"},
{Rollno: "3344",Name: "ghi",Uni: "wxy"}
];
$scope.save=function(){
$scope.students.push({
Rollno: $scope.new_rollno,
Name: $scope.new_name,
Uni: $scope.new_uni
});
$scope.new_rollno="";
$scope.new_name="";
$scope.new_uni=""
};
$scope.checked=[];
$scope.remove=function(index){
alert($scope.checked);
$scope.students.splice(function(record){
return $scope.checked[$index];
},1);
};
};
最佳答案
代码中的主要问题:splice 的第一个参数- 应该是起始索引，但您尝试传递函数。如果使用传递的 index 一切正常
$scope.students.splice(index,1);
在代码片段中，您可以看到即使删除最后一行 - 一切正常
angular.module('app', [])
.controller('tableCtrl', ['$scope',
function($scope) {
$scope.students = [{
Rollno: "1122",
Name: "abc",
Uni: "res",
color: "red"
}, {
Rollno: "2233",
Name: "def",
Uni: "tuv",
color: "red"
}, {
Rollno: "23432",
Name: "g325325hi",
Uni: "wxy"
}, {
Rollno: "3344",
Name: "ghi",
Uni: "wxy"
}];
$scope.save = function() {
$scope.students.push({
Rollno: $scope.new_rollno,
Name: $scope.new_name,
Uni: $scope.new_uni
});
$scope.new_rollno = "";
$scope.new_name = "";
$scope.new_uni = ""
};
$scope.checked = [];
$scope.remove = function(index) {
$scope.students.splice(index, 1);
};
}
