我在点击选择区域有javascript函数(使用Raphael)。双击此功能应添加marker(pin.png)。
window.onload = function () {
var R = Raphael("paper", 500, 500);
var attr = {
fill: "#EEC7C3",
stroke: "#E0B6B2",
"stroke-width": 1,
"stroke-linejoin": "round"
};
var area = {};
area.Element1 = R.path("...").attr(attr);
area.Element2 = R.path("...").attr(attr);
...
area.Element63 = R.path("...").attr(attr);
var current = null;
$("#paper").ondblclick = function (e) {
var relativeX = e.pageX;
var relativeY = e.pageY;
R.image("pin.png", relativeX, relativeY, 22, 22);
};
for (var state in area) {
area[state].color = Raphael.getColor();
(function (st, state) {
st[0].active = 0;
st[0].style.cursor = "pointer";
st[0].onmouseover = function () {
current && area[current].animate({ fill: "#EEC7C3", stroke: "#E0B6B2" }, 500) && (document.getElementById(current).style.display = "");
st.animate({ fill: st.color, stroke: "#ccc" }, 500);
st.toFront();
R.safari();
document.getElementById(state).style.display = "block";
current = state;
};
st[0].onmouseout = function () {
if (this.active == 0)
st.animate({ fill: "#EEC7C3", stroke: "#E0B6B2" }, 500);
else
st.animate({ fill: "#C05219", stroke: "#E0B6B2" }, 500);
st.toFront();
R.safari();
};
st[0].onclick = function () {
st.animate({ fill: "#C05219", stroke: "#E0B6B2" }, 500);
st.toFront();
if (this.active == 0)
this.active = 1;
else
this.active = 0;
R.safari();
};
})(area[state], state);
}
};
我遇到不同浏览器的问题:
我必须让它在Firefox和IE中运行。我能做些什么才能让它发挥作用 - 特别是在Firefox中?
非常感谢任何帮助!

不支持在任何元素上放置click
和dblclick
处理程序。
如果没有特殊的自定义处理,您可能无法正常工作,即使这样也无法正常工作,因为浏览器双击时间是用户可配置的。它通常会导致可访问性问题,并且通常会导致糟糕的用户体验。
来自the docs:
不建议将处理程序绑定到同一元素的click和dblclick事件。触发的事件序列因浏览器而异,有些事件在dblclick之前接收到两个点击事件,而其他事件只接收一个事件。双击灵敏度(双击检测到的点击之间的最长时间)可能因操作系统和浏览器而异,并且通常可由用户配置。

如果必须同时使用单击和双击,则可以尝试添加计时器。它看起来像这样:
window.onload = function () {
var R = Raphael("paper", 500, 500);
var attr = {
fill: "#EEC7C3",
stroke: "#E0B6B2",
"stroke-width": 1,
"stroke-linejoin": "round"
};
var area = {};
area.Element1 = R.path("...").attr(attr);
area.Element2 = R.path("...").attr(attr);
...
area.Element63 = R.path("...").attr(attr);
var current = null;
var timer;
var firing = false;
var singleClick = function () { };
var doubleClick = function () { };
var firingFunc = singleClick;
for (var state in area) {
area[state].color = Raphael.getColor();
(function (st, state) {
st[0].active = 0;
st[0].style.cursor = "pointer";
st[0].onclick = function (event) {
if (firing) {
var relativeX = event.pageX - 10;
var relativeY = event.pageY - 25;
R.image("pin.png", relativeX, relativeY, 22, 22);
$('#status2').html(relativeX + ', ' + relativeY);
firingFunc = doubleClick;
if (this.active == 0) {
this.active = 1;
st.animate({ fill: "#C05219", stroke: "#E0B6B2" }, 500);
st.toFront();
}
else {
this.active = 0;
st.animate({ fill: "#EEC7C3", stroke: "#E0B6B2" }, 500);
st.toFront();
}
R.safari();
return;
}
firing = true;
timer = setTimeout(function () {
firingFunc();
firingFunc = singleClick;
firing = false;
}, 250);
if (this.active == 0) {
this.active = 1;
st.animate({ fill: "#C05219", stroke: "#E0B6B2" }, 500);
st.toFront();
}
else {
this.active = 0;
st.animate({ fill: "#EEC7C3", stroke: "#E0B6B2" }, 500);
st.toFront();
}
R.safari();
};
})(area[state], state);
}
};
您可以将think添加到doubleClick和singleClick函数。
