by code can show , hide markers.. code not work polylines. when page loading lines automaticly loaded.. can suggest how toggle polylines in googlemap?
thanks.
p.s. sorry english
var mycoordslenght = 6; var gmarkers = []; function show(category) { (var i=0; i<gmarkers.length; i++) { if (gmarkers[i].mycategory == category) { if (!gmarkers[i].getmap()) gmarkers[i].setmap(map); gmarkers[i].setvisible(true); } } // == check checkbox == document.getelementbyid(category+"box").checked = true; } function hide(category) { (var i=0; i<gmarkers.length; i++) { if (gmarkers[i].mycategory == category) { gmarkers[i].setvisible(false); } } document.getelementbyid(category+"box").checked = false; infowindow.close(); } function boxwclick(box,category) { if (box.checked) { show(category); } else { hide(category); } } function load() { var myoptions = { zoom: 7, center: new google.maps.latlng(40.0000, 48.0000), maptypecontrol: true, maptypecontroloptions: { style: google.maps.maptypecontrolstyle.dropdown_menu }, zoomcontrol: true, zoomcontroloptions: { style: google.maps.zoomcontrolstyle.small }, maptypeid: google.maps.maptypeid.hybrid, } map = new google.maps.map(document.getelementbyid("map"), myoptions); var infowindow = new google.maps.infowindow; downloadurl("all.php", function(doc) { alert('lines loaded..'); var g = google.maps; var xmldoc = xmlparse(doc); bounds = new google.maps.latlngbounds(); // ========= process polylines =========== var lines = xmldoc.documentelement.getelementsbytagname("line"); // read each line (var = 0; < lines.length; a++) { // line attributes var colour = lines[a].getattribute("colour"); var width = parsefloat(lines[a].getattribute("width")); var diameter = lines[a].getattribute("diameter"); var project = lines[a].getattribute("projectid"); var type = lines[a].getattribute("type"); var contract = lines[a].getattribute("contract"); var cr = lines[a].getattribute("contractor"); if (cr) {cr1 = " " + cr + " ";} else { cr1 = "none";} var comp = lines[a].getattribute("complated"); var category = lines[a].getattribute("rayon"); var id = lines[a].getattribute("id_line"); var html = "<b>contractor:</b> " + cr1 + " </a> <br/> <b> contract: </b>" + contract + " <br/><b>line segment:</b> " + id + " <br/><b>project: </b>" + project +"<br/> <b>diameter: </b>" + diameter + " <br/> <b>completed: </b>" + comp + "% <hr><br/><a class=\"inline-link-1\" href=\"javascript:void(0)\"onclick=\"window.open('cdatal.php?id="+ id +"','cdatal','height=300, width=460,scrollbars=no')\">change completed</a> <a class=\"inline-link-1\" href=\"javascript:void(0)\"onclick=\"window.open('dedit.php?id="+ id +"','cdata','height=300, width=350,scrollbars=no')\">design data</a>" ; // read each point on line var points = lines[a].getelementsbytagname("point"); var pts = []; var length = 0; var point = null; (var = 0; < points.length; i++) { pts[i] = new g.latlng(parsefloat(points[i].getattribute("lng")), parsefloat(points[i].getattribute("lat"))); if (i > 0) { length += pts[i-1].distancefrom(pts[i]); if (isnan(length)) { alert("["+i+"] length="+length+" segment="+pts[i-1].distancefrom(pts[i])) }; } bounds.extend(pts[i]); point = pts[parseint(i/2)]; } // length *= 0.000621371192; // miles/meter if (comp < 1) { colorr = '#fa0505' } if (comp > 0 && comp < 25 ) { colorr = '#ffa640' } if (comp > 24 && comp < 50) { colorr = '#fffd91' } if (comp > 49 && comp < 75) { colorr = '#e8e400' } if (comp > 74 && comp < 100) { colorr = '#bfffad' } if (comp == 100) { colorr = '#0f8500' } if(type == 'dl') {en = '1'} if(type == 'ml') {en = '3'} if(type == 'tl') {en = '5'} var marker = new g.polyline({ map:map, path:pts, strokecolor:colorr, strokeweight:en, clickable: true }); marker.mycategory = category; marker.myname = name; gmarkers.push(marker); bindinfowindow(marker, map, infowindow, html); } map.fitbounds(bounds); }); function bindinfowindow(marker, map, infowindow, html, category) { google.maps.event.addlistener(marker, 'click', function() { infowindow.setcontent(html); infowindow.open(map, marker); }); } /***************************************************************/ } html:
