[英]How to set the multi-slot transclude scope to directive scope?
I'm trying to build the multi-slot directive that may be used recursively. 我正在尝试构建可以递归使用的多槽指令。
THE PROBLEM is how to set the transclude scope to the directive scope of each transclude slot. 问题是如何将transclude范围设置为每个transclude槽的指令范围。
In the directive template I use construct like this: 在指令模板中,我使用如下构造:
<div>
<div ng-tranclude="slot1"></div>
<div ng-tranclude="slot2"></div>
</div>
NOW the standard setting of transclude scope as calling the transclude in link function: 现在,将transclude范围的标准设置调用为链接函数中的transclude:
transclude(scope, function(clone, scope) {
element.append(clone);
});
stopped working. 停止工作。
Let the directive template be: 让指令模板为:
.directive("verticalSplitter", ['$log', function ($log) {
return {
restrict: 'E',
scope: {
width: '=',
height: '=',
split: '=',
minLeft: '=',
minRight: '='
},
transclude: {
leftPane: 'leftPane',
rightPane: 'rightPane'
},
template: '<div style="position:relative; width:{{width}}px; height:{{height}}px;">'
+ '<div style="width:{{splitPosition - 4}}px; height:{{height}}px; position:relative; border: 1px solid black; margin-right: 4px; padding: 4px 4px 4px 4px; display:inline-block;">'
+ '<div style="display:block; overflow:hidden; width:{{splitPosition -12}}px; height:{{height-10}}px; vertical-position:top;" ng-transclude="leftPane"></div>'
+ '</div>'
+ '<div style="position:absolute; left:5px; top:0px; width:{{wsplitPosition -10}}px; bottom:0px; background-color:darkgreen; opacity:0.5; z-index:10000;" ng-show="isMouseDown"></div>'
+ '<div style="position:absolute; left:{{wsplitPosition -2}}px; top:0px; width:4px; bottom:0px; background-color:{{resizeBarColor}}; z-index:10000; cursor:col-resize;" ng-mousedown="resizeMouseDown($event)"></div>'
+ '<div style="position:absolute; left:{{wsplitPosition + 4}}px; top:0px; width:{{width - wsplitPosition -16}}px; bottom:0px; background-color:darkred; opacity:0.5; z-index:10000;" ng-show="isMouseDown"></div>'
+ '<div style="width:{{width - splitPosition - 8}}px; height:{{height}}px; position:relative; border: 1px solid black; margin-right: 4px; padding: 4px 4px 4px 4px; display:inline-block;">'
+ '<div style="display:block; overflow:hidden; vertical-position:top; width:{{width - splitPosition - 16}}px; height:{{height - 10}}px;" **ng-transclude="rightPane"**></div>'
+ '</div>'
+ '</div>',
link: function (scope, element, attrs, controller, transcludeFn) {
scope.splitPosition = scope.split;
scope.wsplitPosition = scope.splitPosition;
scope.resizeBarColor = "transparent";
var startX = 0;
scope.isMouseDown = false;
var updateRL = function () {
scope.widthL = scope.splitPosition - 12;
scope.heightL = scope.height - 10;
scope.widthR = scope.width - scope.splitPosition - 16;
scope.heightR = scope.height - 10;
};
updateRL();
scope.resizeMouseDown = function ($event) {
scope.isMouseDown = true;
scope.resizeBarColor = "dimgray";
startX = $event.screenX;
$(window).on("mousemove", function (event) {
scope.doResize(event);
scope.$apply();
return false;
});
$(window).on("mouseup", function (event) {
$(window).off("mouseup");
$(window).off("mousemove");
scope.resizeMouseUp(event);
scope.$apply();
return false;
});
};
scope.resizeMouseUp = function ($event) {
scope.splitPosition = scope.wsplitPosition;
updateRL();
scope.resizeBarColor = "transparent";
scope.isMouseDown = false;
};
scope.doResize = function ($event) {
if (!scope.isMouseDown)
return;
var ev = $event;
var moveX = (startX - $event.screenX);
if (scope.wsplitPosition - moveX > scope.minLeft && (scope.wsplitPosition - moveX) < scope.width - scope.minRight) {
scope.wsplitPosition -= (startX - $event.screenX);
startX = $event.screenX;
}
return false;
};
}
};
}])
when using slots, you have to specify what your interested in. 使用插槽时,您必须指定您感兴趣的内容。
The transclude function signature looks like this: transclude函数签名如下所示:
transclude([scope], cloneLinkingFn, futureParentElement, slotName)
transclude(scope, function(clone, scope) {
element.append(clone);
}, false, 'slot1');
