常用函数

new Date($scope.reg.birthday)=="Invalid Date"

Angular 常用

ng-repeat，ng-repeat-start，ng-repeat-end，ng-value，ng-init

<p ng-repeat="itemSec in itemsub.orderOptionItems" ng-if="$index % 2 ==0" >
<span ng-if="$index+0<itemsub.orderOptionItems.length">&nbsp;&nbsp;{{itemsub.orderOptionItems[$index+0].optionDetail |to_trusted}} </span>
<span ng-if="$index+1<itemsub.orderOptionItems.length">&nbsp;&nbsp;{{itemsub.orderOptionItems[$index+1].optionDetail |to_trusted}}</span>
</p>

.filter('to_trusted', function(){
return function(value) {
var reg=new RegExp("<[^>]+>","g");
if(!!value){
return value.replace(reg,"");
}else{
return "";
}

}
})

.filter('abs', function () {
return function(val) {
return Math.abs(val);
}
})

{{items.balance | abs | number:2 }}
{{ aa |to_trusted}}

return function(a, params) {

if (params) {
return $filter('filter')(a, params);
} else {
return [];
}
}
<li ng-repeat='name in names | nonBlankFilter:q'> {{name}} </li>
<input ng-model='q' />

去重Array还有更简单

function unique5(array){
  var r = [];
  for(var i = 0, l = array.length; i < l; i++) {
    for(var j = i + 1; j < l; j++)
      if (array[i] === array[j]) j = ++i;
    r.push(array[i]);
  }
  return r;
}

Array.prototype.unique3 = function () {
    // 构建一个新数组存放结果
    var newArray = [];
    // 创建一个空对象
    var object = {};
    // for循环时，每次取出一个元素与对象进行对比
    // 如果这个元素不重复，则将它存放到结果数中
    // 同时把这个元素的内容作为对象的一个属性，并赋值为1,
    // 存入到第2步建立的对象中
    for (var i = 0; i < this.length; i++){
        // 检测在object对象中是否包含遍历到的元素的值
        if(!object[typeof(this[i]) + this[i]]) {
            // 如果不包含，将存入对象的元素的值推入到结果数组中
            newArray.push(this[i]);
            // 如果不包含，存入object对象中该属性名的值设置为1
            object[typeof(this[i]) + this[i]] = 1;
        }
    }
    return newArray;
}

但在ES6去重还有更简单，更优化的方案，比如：

// ES6
function unique (arr) {
    const seen = new Map()
    return arr.filter((a) => !seen.has(a) && seen.set(a, 1))
}
// or
function unique (arr) {
    return Array.from(new Set(arr))
}
