------------
注:
viewCount 指显示的页码数量,如(上一页,2,3,4,5,6,7,8,下一页)
设viewCount = 7
测试结果
输入当前页码1,总页数1 ,显示页码标签 $scope.pages = [];
输入当前页码1,总页数2 ,显示页码标签 $scope.pages = [1,2];
输入当前页码1,总页数3 ,显示页码标签 $scope.pages = [1,2,3];
输入当前页码1,总页数4 ,显示页码标签 $scope.pages = [1,2,3,4];
输入当前页码1,总页数5 ,显示页码标签 $scope.pages = [1,2,3,4,5];
输入当前页码1,总页数6 ,显示页码标签 $scope.pages = [1,2,3,4,5,6];
输入当前页码1,总页数7 ,显示页码标签 $scope.pages = [1,2,3,4,5,6,7];
输入当前页码5,总页数8 ,显示页码标签 $scope.pages = [2,3,4,5,6,7,8];
输入当前页码6,总页数9 ,显示页码标签 $scope.pages = [3,4,5,6,7,8,9];
输入当前页码7,总页数8 ,显示页码标签 $scope.pages = [4,5,6,7,8];
angularjs 的directive定义
.directive('noenter',function() {
return function(scope, element) {
element.on('keypress', function(e) {
if (e.which === 13) {
var page = element.val();
if(page>=1&&page<=scope.totalPage){
return scope.getData(page);
}else{
alert('输入页码超出范围!');
}
}
return true;
})
}
})
使用:
<input type="text" noenter class="goto-page">
