jquery.$.ajax简单的使用

function LoadWFS()
{
var viewer = new Cesium.Viewer('cesiumContainer');
$.ajax({
url: "http://localhost/SG/streamer.ashx?&VERSION=1.0.0&Service=WFS&Username=&Password=&TYPENAME=cc.398445&request=GetFeature",
cache: false,
async: true,
success: function (data) {
alert(data.childNodes[0].childNodes.length);
//alert(data.childNodes[0].childNodes[1].childNodes[0].childNodes[0].childNodes[0].childNodes[0].firstChild.nodeValue);
viewer.entities.removeAll();
for (var i = 1; i < data.childNodes[0].childNodes.length; i++) {
var gxyz = data.childNodes[0].childNodes[i].childNodes[0].childNodes[0].childNodes[0].childNodes[0].firstChild.nodeValue;

var geo = gxyz.split(',');

var position = Cesium.Cartesian3.fromDegrees(parseFloat(geo[0]), parseFloat(geo[1]), parseFloat(geo[2]));
var heading = Cesium.Math.toRadians(135);
var pitch = 0;
var roll = 0;
var hpr = new Cesium.HeadingPitchRoll(heading, pitch, roll);
var orientation = Cesium.Transforms.headingPitchRollQuaternion(position, hpr);

createModel(parseFloat(geo[0]), parseFloat(geo[1]), 'http://localhost/SG/TerraExplorerWeb/models/Cesium_Air.glb', 1000);

};
viewer.flyTo(viewer.entities);
},
error: function (data) {
alert(data);
}
});

}
