How to call a function, if the width of the component's DOM element is changed? (Angular4)

由 随声附和 提交于 2019-12-08 08:20:42
问题 I have to recalculate something, if the width component's DOM element is changed. Without Angular, I solved it like this: var old_width = $("#container").width(); update(); $(window).on('resize',function() { var new_width = $("#container").width(); if(old_width != new_width) { old_width = new_width; update(); } }); I would like to solve this with Angular. Unfortunately there is no resize event for regular elements, but I would like to listen somehow for it. I could use setInterval or window

Fade In circles in Google Maps

由 女生的网名这么多〃 提交于 2019-12-08 06:15:25
问题 On my map, I have it so that a node/circle is drawn at a certain location, and when this node is clicked, other related nodes appear nearby. However, I'd like to have them fade in after about one second instead of just appearing suddenly. I already had a look at this solution, but I couldn't really understand how it would translate over to my code. Is there an easy way to do this? ... function initialize() { for(var num = 0; num < lat.length; num++) { nodeInfo[num] = { center: new google.maps

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last month .

问题 I am having what I thought was a simple problem, but after about a week of searching for the solution I can't seem to find the reason behind it. Basically I am calling the function below every time the mouse is clicked, and it works fine in Chrome, but in Firefox the alert("This is not called") never gets called. I know the problem is in the two lines of code: x = event.pageX - canvas.offsetLeft; y = event.pageY - canvas.offsetTop; but can't seem to find whats wrong. Mozillas site says that

Chrome - Javascript prevent default Ctrl + MouseWheel behavior

问题 I'm trying to prevent the default Ctrl + MouseWheel zoom behavior in Chrome with JavaScript, for the other browsers I use preventDefault() and stopPropagation() in the callback function for mouse-wheel event and works perfect because the other browser always trigger a mouse-wheel event but Chrome does not.
