Ama*_*mar 6 javascript jquery contextmenu ios
我在.html示例中使用了contextMenu事件,当我长按DIV时它会被触发,但是现在它无法正常工作.在最新的IOS 8.2版本中有什么问题.这是示例代码,
<head>
<title></title>
<script src="Scripts/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#content").on("contextmenu", function () {
alert("CM");
});
});
</script>
</head>
<body>
<div id="content" style="height:300px; width:300px; background-color:gray;"></div>
</body>

这是工作样本
请有人帮我这个.
基本上,在 iOS 上,触摸事件不会被模拟为鼠标事件。改用触摸事件:“touchstart”、“touchmove”和“touchend”。
在您的情况下,在 iOS 上与 Android 相反,长时间触摸屏幕时不会触发“上下文菜单”。要在 iOS 上自定义长按,您应该使用以下内容:
// Timer for long touch detection
var timerLongTouch;
// Long touch flag for preventing "normal touch event" trigger when long touch ends
var longTouch = false;
$(touchableElement)
.on("touchstart", function(event){
// Prevent default behavior
event.preventDefault();
// Test that the touch is correctly detected
alert("touchstart event");
// Timer for long touch detection
timerLongTouch = setTimeout(function() {
// Flag for preventing "normal touch event" trigger when touch ends.
longTouch = true;
// Test long touch detection (remove previous alert to test it correctly)
alert("long mousedown");
}, 1000);
})
.on("touchmove", function(event){
// Prevent default behavior
event.preventDefault();
// If timerLongTouch is still running, then this is not a long touch
// (there is a move) so stop the timer
clearTimeout(timerLongTouch);
if(longTouch){
longTouch = false;
// Do here stuff linked to longTouch move
} else {
// Do here stuff linked to "normal" touch move
}
})
.on("touchend", function(){
// Prevent default behavior
event.preventDefault();
// If timerLongTouch is still running, then this is not a long touch
// so stop the timer
clearTimeout(timerLongTouch);
if(longTouch){
longTouch = false;
// Do here stuff linked to long touch end
// (if different from stuff done on long touch detection)
} else {
// Do here stuff linked to "normal" touch move
}
});

这是一个解释(除其他外)触摸事件在每个操作系统上都不会被模拟为鼠标事件的页面:http : //www.html5rocks.com/en/mobile/touchandmouse/
希望这会有所帮助,我花了很长时间才弄明白;)
