问题描述
我希望对gmaps4rails中的显示/隐藏功能有一点了解。
I'm hoping to get a little bit of insight on show / hide functionality in gmaps4rails.
// == shows all markers of a particular category, and ensures the checkbox is checked ==
function show(category) {
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].mycategory == category) {
gmarkers[i].setVisible(true);
}
}
// == check the checkbox ==
document.getElementById(category+"box").checked = true;
}
// == hides all markers of a particular category, and ensures the checkbox is cleared ==
function hide(category) {
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].mycategory == category) {
gmarkers[i].setVisible(false);
}
}
// == clear the checkbox ==
document.getElementById(category+"box").checked = false;
// == close the info window, in case its open on a marker that we just hid
infowindow.close();
}
// == a checkbox has been clicked ==
function boxclick(box,category) {
if (box.checked) {
show(category);
} else {
hide(category);
}
// == rebuild the side bar
makeSidebar();
}
function myclick(i) {
google.maps.event.trigger(gmarkers[i],"click");
}
// == rebuilds the sidebar to match the markers currently displayed ==
function makeSidebar() {
var html = "";
for (var i=0; i<gmarkers.length; i++) {
if (gmarkers[i].getVisible()) {
html += '<a href="javascript:myclick(' + i + ')">' + gmarkers[i].myname + '<\/a><br>';
}
}
document.getElementById("side_bar").innerHTML = html;
}
所以,在我的控制器中,我构建了一个标记列表,包括其类别为json。
So, in my controller, I'm building a list of markers, and including their categories as json.
@markersLoc = @locSearch.to_gmaps4rails do |loc, marker|
letter.next!
marker_image = "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=#{letter}|82ABDD|000000"
marker.infowindow render_to_string(partial: '/events/info',
locals: {object: loc})
marker.picture({picture: marker_image,
width: 32,
height: 32,
marker_anchor: [11,30],
shadow_picture: "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
shadow_width: 110,
shadow_height: 110,
shadow_anchor: [12,34]})
marker.title loc.what
marker.sidebar render_to_string(partial: '/events/sidebar',
locals: {object: loc, letter: marker_image})
marker.json({cat: loc.category})
end
我有点卡住了,在这里。我知道:cat
字符串可用(例如:1,3,4),但我不确定如何使用它来实现我之后的操作。 / p>
I'm kind of stuck, here. I know the :cat
string is available (ex: 1,3,4), but I'm not sure how to use it to achieve what I'm after.
推荐答案
几乎可以使用那里的内容,并做了一些修改。这给了我9个类别的功能(可以更多或更少),并只查看我想要的。真棒。
Was able to pretty much use what was there, with some modification. This gave me functionality to have 9 categories (could be more or less), and only view what I want. Awesome.
// == shows all markers of a particular category, and ensures the checkbox is checked ==
function show(category) {
var regEx = new RegExp("[" + category + "]")
for (var i=0; i<Gmaps.map.markers.length; i++) {
if (Gmaps.map.markers[i].cat) {
if (Gmaps.map.markers[i].cat.match(regEx)) {
Gmaps.map.showMarker(Gmaps.map.markers[i]);
}
}
}
// == check the checkbox ==
document.getElementById(category+"box").checked = true;
}
// == hides all markers of a particular category, and ensures the checkbox is cleared ==
function hide(category) {
var regEx = new RegExp("[" + category + "]")
for (var i=0; i<Gmaps.map.markers.length; i++) {
if (Gmaps.map.markers[i].cat) {
if (Gmaps.map.markers[i].cat.match(regEx)) {
Gmaps.map.hideMarker(Gmaps.map.markers[i]);
}
}
}
// == clear the checkbox ==
document.getElementById(category+"box").checked = false;
// == close the info window, in case its open on a marker that we just hid
// Gmaps.map.infowindow.close();
}
// == a checkbox has been clicked ==
function boxclick(box,category) {
if (box.checked) {
show(category);
} else {
hide(category);
}
}
