我正在尝试为svg元素设置onmousemove事件。下面的代码适用于chrome,但在firefox中,它并不是每次都正确设置onmousemove属性。在第二次更改后,它变得混乱。
mysvg.setAttribute('onmousemove','window.updateXY(evt,' + that.chartNumber + ')');
根据firebug,mysvg仍然是正确的svg元素:svg#chart0
svg属性onmousemove表示函数(e)而不是onmousemove(evt),当它搞砸了,但是在firebug中没有报告错误
编辑以显示更多代码:
var YAxis = function(mysvg,chartNumber){
this.chartNumber = chartNumber;
var that = this;
var g = document.createElementNS(xmlns, "g");
this.id = 'YAxis' + chartNumber;
g.id = this.id;
mysvg.appendChild(g);
var shift = false;
this.selected = false;
this.yScale = function(e){
e.stopPropagation();
that.origY = e.pageY;
that.shift = e.ctrlKey;
mysvg.onmousemove = that.dragY;
mysvg.onmouseup = that.dropY;
}
this.dragY = function(e) {
var chart = charts[that.chartNumber];
if(chart.log)
displayXYText.innerHTML = 'range: ' + Math.round(Math.pow(10,chart.max*(1 + (e.pageY - that.origY)/(chart.height)))*100)/100 + '-' + Math.round(Math.pow(10,chart.min*(1 - (e.pageY - that.origY)/(chart.height)))*100)/100;
else
displayXYText.innerHTML = 'range: ' + Math.round(chart.max*(1 + (e.pageY - that.origY)/(chart.height))*100)/100 + '-' + Math.round(chart.min*(1 - (e.pageY - that.origY)/(chart.height))*100)/100;
}
this.dropY = function(e) {
var chart = charts[that.chartNumber];
if(that.shift){
var range = (chart.max - chart.min)*Math.round((e.pageY - that.origY)/(chart.height)*1000)/1000;
chart.max += range;
chart.min += range;
}else{
var range = chart.max - chart.min;
chart.max *= 1 + Math.round((e.pageY - that.origY)/(chart.height)*1000)/1000;
chart.min *= 1 - Math.round((e.pageY - that.origY)/(chart.height)*1000)/1000;
if(chart.max <= chart.min){
chart.max = chart.min + range;
}
}
mysvg.setAttribute('onmousemove','window.updateXY(event,' + that.chartNumber + ')');
//mysvg.onmousemove = updateXY(e,that.chartNumber);//function() { updateXY(e,that.chartNumber)}; //set back to orig function
//mysvg.setAttribute('onmousemove','updateXY(evt,' + that.chartNumber + ')');
//console.debug(mysvg.onmousemove.textContent);
mysvg.setAttribute('onmouseup','window.mouseUp(event)');
//console.debug("got here onmousemove");
chart.redraw();
}
}

我尝试了上面的所有方法但没有在firefox中正常工作。解决方案是不将event
以外的任何参数传递给updateXY函数。当其他参数未定义时,运行单独的逻辑以确定在这种情况下参数应该是什么。代码位于window
框架后,您可以像平常一样使用setAttribute
。 #FirefoxOOPfail
