创建一个没有 ngRepeat 的列表 [英] Create a list without ngRepeat

问题描述

我想创建一个不需要 ngRepeat 的指令，因为指令上有一些附加功能，与 ngRrepeat 不兼容.

这是我的 ng-repeat 指令:

<ul><li ng-repeat="item in items track by $index" ng-class="attrs.itemTheme" data-item="{{ item[attrs.itemId]}}"><div ng-include="attrs.tpl"></div>

attrs.tpl, nt-dimension 是另一个指令，它使用来自 ngRepeat 的 items 值:

没有 ngRepeat:

<ul></ul>

请给我举个例子，我已经不再为此苦苦挣扎了.

必须编译并附加 ngIncluded 模板，但问题是它只编译最后一个，因为摘要周期很慢.

var el = jqElm.find('ul');scope.attrs.list.forEach(function (vl) {无功 tmp ='<li class="' + attrs.itemTheme + '" data-item="' + vl.id + '">'+'<div ng-include="\'' + attrs.itemTpl + '\'"></div>'+'</li>';scope.item = vl;//这很慢:(var b = $compile(tmp)(scope);el.append(b);});

解决方案

您需要为每个 li 手动创建自己的作用域，因此每个项目都有自己的数据.

var ul = jqElm.find('ul');scope.list.forEach(函数(vl){var li = '<li><div ng-include="\'item-tpl2.html\'"></div></li>';var newScope = scope.$new();newScope.item = vl;var cLi = $compile(li)(newScope);ul.append(cLi);

I would like to create a directive, that does not need ngRepeat, because there is some additional functionality on the directive, that doesn't play good with ngRrepeat.

This is my directive with ng-repeat:

<div>
<ul>
    <li ng-repeat="item in items track by $index" ng-class="attrs.itemTheme" data-item="{{ item[attrs.itemId]}}">
        <div ng-include="attrs.tpl"></div>
    </li>
</ul>
</div>

attrs.tpl, nt-dimension is another directive, that uses the items values from ngRepeat:

<script type="text/ng-template" id="dimension-item-tpl.html">
    <div nt-dimension x-attrs="item"></div>
</script>

Without ngRepeat:

<div> 
   <ul></ul>
</div>

Can some please give me an example, I am quit struggling with this.

Got to compile and append the ngIncluded template, but the problem is, that it compiles only the last one, because the digest cycle is to slow.

var el = jqElm.find('ul');
scope.attrs.list.forEach(function (vl) {
    var tmp = 
        '<li class="' + attrs.itemTheme + '" data-item="' + vl.id + '">' +
            '<div ng-include="\'' + attrs.itemTpl + '\'"></div>' +
                '</li>';

    scope.item = vl; // this is to slow :(

    var b = $compile(tmp)(scope);
    el.append(b);
});

解决方案

You need to manually create an own scope for each li, so each item has its own data.

var ul = jqElm.find('ul');

scope.list.forEach(function (vl) {
var li = '<li><div ng-include="\'item-tpl2.html\'"></div></li>';
var newScope = scope.$new();
newScope.item = vl;
var cLi = $compile(li)(newScope);
ul.append(cLi);
