角JS可调整大小的div指令 [英] Angular JS resizable div directive
问题描述
我的网站将有多个部分,每一个我打算改变大小。要做到这一点,我做了一个调整大小指令,例如:
My site will have multiple sections, each of which I intend to be resizable. To accomplish this I've made a "resizable" directive, e.g.:
<div class="workspace" resize="full" ng-style="resizeStyle()">
<div class="leftcol" resize="left" ng-style="resizeStyle()">
通过一项指令,看起来是这样的:
With a directive that looks something like:
lwpApp.directive('resize', function ($window) {
return {
scope: {},
link: function (scope, element, attrs) {
scope.getWinDim = function () {
return {
'height': window.height(),
'width': window.width()
};
};
// Get window dimensions when they change and return new element dimensions
// based on attribute
scope.$watch(scope.getWinDim, function (newValue, oldValue) {
scope.resizeStyle = function () {
switch (attrs.resize) {
case 'full':
return {
'height': newValue.height,
'width': (newValue.width - dashboardwidth)
};
case 'left':
return {
'height': newValue.height,
'width': (newValue.width - dashboardwidth - rightcolwidth)
};
etc...
};
}, true);
//apply size change on window resize
window.bind('resize', function () {
scope.$apply(scope.resizeStyle);
});
}
};
});
正如你所看到的,这只是调整大小的窗口大小调整每个div,每个指令具有分离的范围。这工作得很好什么它的建成为,但最终我想提出通过拖动条可调整大小的div的一个子集。例如
As you can see, this only resizes each div on window resize, and each directive has an isolate scope. This works fine for what it's built for, but ultimately I would like to make a subset of the divs resizable via a draggable bar. For instance
div1 div2
----------------
| || |
| || |
| || |
| || |
----------------
draggable bar in middle
在可拖动条的移动(在水平方向),我需要访问这两个DIV1,通过父控制器的范围DIV2的宽度presumably(?)。我的问题是:
On the the draggable bar's movement (in the horizontal direction), I would need to access both div1, div2's width presumably via the scope of a parent controller(?). My questions are:
1),这是正确的方式去在angluar使得可调整大小的div?特别是,当一个分区的大小会影响另一
1) Is this the "correct" way to go about making resizable divs in angluar? In particular, when the size of one div affects another?
2)我个人觉得像答案(1)不,我没有做正确,因为我不能指令之间通信时,每个人都有一个分离的范围。如果这是真的,我怎么能解释的div之间了窗口和调整大小拖动?
2) I personally feel like the answer to (1) is "No, I am not doing it correctly because I cannot communicate between directives when each has an isolate scope." If this is true, how can I account for both window and draggable resizing between divs?
非常感谢您有任何帮助!
Thanks so much for any help you have have!
推荐答案
这个问题是老了,但任何人寻找一个解决方案,我建立了一个简单的指令来处理这个问题,垂直和水平的调节大小。
This question is old, but for anybody looking for a solution, I built a simple directive to handle this, for vertical and horizontal resizers.
angular.module('mc.resizer', []).directive('resizer', function($document) {
return function($scope, $element, $attrs) {
$element.on('mousedown', function(event) {
event.preventDefault();
$document.on('mousemove', mousemove);
$document.on('mouseup', mouseup);
});
function mousemove(event) {
if ($attrs.resizer == 'vertical') {
// Handle vertical resizer
var x = event.pageX;
if ($attrs.resizerMax && x > $attrs.resizerMax) {
x = parseInt($attrs.resizerMax);
}
$element.css({
left: x + 'px'
});
$($attrs.resizerLeft).css({
width: x + 'px'
});
$($attrs.resizerRight).css({
left: (x + parseInt($attrs.resizerWidth)) + 'px'
});
} else {
// Handle horizontal resizer
var y = window.innerHeight - event.pageY;
$element.css({
bottom: y + 'px'
});
$($attrs.resizerTop).css({
bottom: (y + parseInt($attrs.resizerHeight)) + 'px'
});
$($attrs.resizerBottom).css({
height: y + 'px'
});
}
}
function mouseup() {
$document.unbind('mousemove', mousemove);
$document.unbind('mouseup', mouseup);
}
};
});
