onclick

问题 I'm having trouble getting an onClick listener to work with a dc.barChart. According to this thread, clickable charts should have an onClick listener now. However, I've tried both chart.onClick = function and chart.on("click", function) without any luck. Below is the code I've tried to test whether the listener is working or not. var hubChart = dc.barChart("#hub-chart"); var dateHub = dateCF.dimension(function(d){ return d.hub;}), dateHubs = dateHub.group().reduceSum(function(d){ return d

问题 Right now I have an app that searches and returns items in a ListFragment. I want to be able to make each ListFragment clickable, such that when it is clicked, a new activity starts using something like this: public void onListItemClick(ListView listView, View view, int position, long id) { Intent i = new Intent(this, PlaceView.class); startActivity(i); //eventually data from the List will be passed to the new Activity... } The class that starts the ListFragment that I need to be clickable is

问题 @HostListener OnClick does not work in firefox. I tried onClick, onclick and onGlobalClick. They all work in chrome but no one in firefox. Here is my code: constructor(private elRef: ElementRef, private renderer: Renderer2) { } @Output() offClick = new EventEmitter(); @HostListener('document:click', ['$event.path']) public onGlobalClick(targetElementPath: Array<any>) { const elementRefInPath = targetElementPath.find(e => e === this.elRef.nativeElement); if (!elementRefInPath) { this.offClick

问题 Is there a way to have 1 onClick Lister for many buttons where I can toss a case statement to do things based on what buttons were clicked. I know I can make 100 different listeners for 100 buttons but I have to think I can create some nifty variables to do it in less lines of code. 回答1: Button btn1, btn2; public void onCreate(Bundle b) { // here you do normal things like assigning a // content view to the activity, initiate buttons, etc. // then you assign the same listener to both buttons

问题 I'm trying to make an "Insert link" button to a Rich Text Editor in Javascript. Basically, what it'll do is adding the following code to its content: <a href="linkGoesHere" onClick="someJSFunction();"> textGoesHere </a> The catch is, someJSFunction() must fire when the user clicks on the button inside the editor itself. I wrote a Javascript function which adds that code when the Insert Link button is clicked on, like this: editor.setContent(previousContent + theHtmlCode); However, when I

Possible Duplicate: jQuery - Click event doesn’t work on dynamically generated elements I just have a clickable add button that adds new table rows. The table rows include a delete button.
