[英]onmouseover, onmouseout and onclick logic to show/hide
我在网页上有许多与放大器交互的按钮。 我希望每一个都基于鼠标事件执行三个JavaScript函数之一。
我遇到的问题是,当我单击按钮时,其他行消失了,但是当我将所有行都移出鼠标时,它们又再次显示了。 我需要的是:
onmouseover =悬停时,隐藏不对应的元素,将焦点保持可见。 (出于各种原因,使用不透明度=0。)
onclick =永久隐藏不对应的元素,直到单击另一个按钮。
onmouseout =如果未单击,则显示所有元素,但如果单击,则仅显示焦点元素,直到单击另一个按钮。
您可以在此处查看功能。 他们都工作,只是不确定如何获得我需要的工作。
function resetall(focus) {
features.eachLayer(function(l) {
var props = l.feature.properties;
props['stroke-opacity'] = 1;
});
features.setGeoJSON(geojson);
};
function clickline(focus) {
features.eachLayer(function(l) {
var props = l.feature.properties;
props['stroke-opacity'] = (props.id !== focus) ? 0.5 : 1;
});
features.setGeoJSON(geojson);
};
function showline(focus) {
features.eachLayer(function(l) {
var props = l.feature.properties;
props['stroke-opacity'] = (props.id === focus) ? 1 : 1;
});
features.setGeoJSON(geojson);
};
function updateheader(focus) {
// Iterate through each feature in the ,
// features object and alter the properties.
features.eachLayer(function(l) {
var props = l.feature.properties;
if (props.id === focus) {
props['stroke-opacity'] = (props.id === focus) ? 1 : 1;
map.setView([props['zlat'], props['zlng']], props['zzoom']);
infoTop.innerHTML = '<div>' + props['header'] + '</div>';
info.innerHTML = '<div>' + props['descript'] + '<br>' + '</div>';
infoImg.innerHTML = '<div>' + props['image'] + '<br>' + '</div>';
} else {
props['stroke-opacity'] = (props.id !== focus) ? 0.0 : 1;
}
});
features.setGeoJSON(geojson);
};

希望这是有道理的。 谢谢。

与http://stackoverflow.com/questions/2575420/jquery-binding-event-on-selected-class类似的问题
为HTML对象使用唯一的类名,并使用jquery将事件绑定到具有该类名的所有对象的函数。
我不得不对您的代码进行一些重构,以使其工作并变得更加清晰。 它不完全符合您在请求中描述的内容,但是我想说您应该重新考虑您的期望,因为例如,当您不单击任何触发器时,只需将鼠标悬停一遍,您应该以与以前相同的状态结束徘徊,但在您的描述中却并非如此。
其他说明:
updateheader()
有点混乱,因此为了清楚起见,将其注释掉。 总体而言,该代码现在可以运行,但还远远不够完美。 您可能需要工作在清晰度和更高的抽象水平上,而不是重复代码的相同部分。 祝好运。
