Angular js:如何使用ngMousedown ngMouseup [英] Angular js: how to use ngMousedown ngMouseup
问题描述
是否可以使用ngMousedown将类添加到div,ngMouseup用于再次删除类?
目前我使用 ng-mousedown =activateClass(),在activateClass()中更改 $ scope.className =data-active它再次与ng-mouseup的其他功能。并使用ng-class添加类data-active
我不想使用$ scope.className和更改它与控制器中的函数,因为此函数用于几个div,我不想
通常控制器不应该关心你的DOM。你在那里试图做的似乎更适合一个指令。我将实现一个指令:
app.directive(highlight,function(){
pre>
return function ,element,attrs){
element.on('mouseup',function(event){
element.removeClass(attrs.highlight)
})
element.on mousedown',function(event){
element.addClass(attrs.highlight)
})
}
})
并在这样的div上使用它
div highlight =active>
我的内容在这里
< / div>
其中作为活动是我的css类的名称。
Is it possible to use ngMousedown for adding class to a div and ngMouseup for removing the class again? At the moment I use ng-mousedown="activateClass()" , in activateClass() change $scope.className="data-active" and change it again with other function with ng-mouseup. And use ng-class to add the class "data-active" I don't wanna use $scope.className and change it with function in controller, because this function is used for several divs and I don't want to add the class to all of the divs I have.
Thank you.
解决方案Normally controllers should not care about your DOM. What you are trying to do there seems more like suitable for a directive. I would implement a directive:
app.directive("highlight", function() { return function(scope, element, attrs) { element.on('mouseup', function(event) { element.removeClass(attrs.highlight) }) element.on('mousedown', function(event) { element.addClass(attrs.highlight) }) } })
and use it on a div like this
<div highlight="active"> my content is here </div>
where as active is the name of my css class.
