  $("input:radio[name=\"rdoType\"]").change(function () {
    let selectType = $(this).val()
    switch (selectType) {
      default:
        // Decimal
        $(".viewTen").show()
        $(".viewDms").hide()
        $(".viewGk").hide()
        updateTen()
        break

        break
    }
  })

  $("input:radio[name=\"rdoGkType\"]").change(function () {
    let selectType2 = $(this).val()
    switch (selectType2) {
      default:
        $(".viewGk3").show()
        $(".viewGk6").hide()
        updata3GKZone()
        break
      case "2":
        // Current view range
        $(".viewGk3").hide()
        $(".viewGk6").show()
        updata6GKZone()
        break
    }
  })
}
```

--------------------------------

```javascript
function getQueryString(name) {
  var reg = new RegExp("(^|&)" + name + "=(\[^&］\*)(&|$)")
  var r = window.location.search.substr(1).match(reg)
  if (r != null) {
    return decodeURI(r[2])
  }
  return null
}
```

--------------------------------

### Draw Point Feature

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/turf/buffer/index.html

Clears existing graphics and starts a point drawing mode with specified styles. The drawn point will have a pixel size of 6 and a blue color.

```javascript
function drawPoint() {
  deleteAll()
  graphicLayer.startDraw({
    type: "point",
    style: { pixelSize: 6, color: "#0000ff" }
  })
}
```

--------------------------------

### Initialize UI and Keyboard Event Handling

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/map/manager/keyboardRoam/index.html

Initializes a slider for step control and sets up a keydown event listener to manage active key highlighting and potentially map movement. Requires jQuery and a slider component.

```javascript
function initUI(map) {
$("#step")
.slider({
min: 0,
max: 300,
value: 10
})
.on("change", (e) => {
changeSlider(e.value.newValue)
})
let activeKey = ""
$(document).keydown(function (event) {
// 在这里处理键盘事件
$(".zm_${activeKey}").removeClass("active")
activeKey = event.key
$(".zm_${activeKey}").addClass("active")
})
}
```

--------------------------------

### Activate Attribute Editing Widget

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/graphic/basis/ellipse/index.html

Manages the activation and deactivation of the attribute editing widget. It either starts editing an existing graphic or activates the widget for a new one.

```javascript
    //附加：激活属性编辑widget【非必需，可以注释该方法内部代码】
    let timeTik
    function showEditor(graphic) {
        clearTimeout(timeTik)

### Activate Property Editing Widget

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/layer-graphic/draw/draw/index.html

Manages the activation and deactivation of a property editing widget for graphics. It handles starting the editing process and ensuring the widget is properly managed.

```javascript
//附加：激活属性编辑widget【非必需，可以注释该方法内部代码】
let timeTik
function startEditing(graphic) {
  clearTimeout(timeTik)
  let plotAttr = es5widget.getClass("widgets/plotAttr/widget.js")
  if (plotAttr && plotAttr.isActivate) {
    plotAttr.startEditing(graphic, graphic.coordinates)
  } else {
    es5widget.activate({
      map: map,
      uri: "widgets/plotAttr/widget.js",
      name: "属性编辑",
      graphic: graphic,
      lonlats: graphic.coordinates
    })
  }
}

function stopEditing() {
  timeTik = setTimeout(function () {
    es5widget.disable("widgets/plotAttr/widget.js")
  }, 200)
}
```

### UI Initialization and Tab Switching

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/query/arcgisPolygon/index.html

This function initializes the user interface, including setting up click handlers for query and clear buttons. It also implements the logic for switching between different content views (table, pie chart, bar chart) based on user clicks on tab list items.

```javascript
//table栏切换Ui
function initUI() {
    $("#query").click(function () {
        let queryVal = $.trim($("#queryText").val())
        queryData(queryVal)
    })
    $("#clearAll").click(function () {
        $("#tab_check").hide()
        clearAll()
    })
    let tab_list = document.querySelector(".tab_list")
    let lis = tab_list.querySelectorAll("li")
    let item = document.querySelectorAll(".item")
    for (let i = 0; i < lis.length; i++) {
        lis[i].setAttribute("index", i)
        lis[i].onclick = function () {
            for (let i = 0; i < lis.length; i++) {
                lis[i].className = ""
            }
            this.className = "current"
            let index = this.getAttribute("index")
            for (let j = 0; j < item.length; j++) {
                item[j].style.display = "none"
            }
            item[index].style.display = "block"
        }
    }
}
```

### Activate Attribute Editor Widget

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/graphic/basis/polyDecorator/index.html

Manages the activation and interaction with the attribute editor widget. It either starts editing an existing graphic or activates the widget to create a new one.

```javascript
let timeTik
function showEditor(graphic) {
 clearTimeout(timeTik)
 let plotAttr = es5widget.getClass("widgets/plotAttr/widget.js")
 if (plotAttr && plotAttr.isActivate) {
 plotAttr.startEditing(graphic, graphic.coordinates)
 } else {
 es5widget.activate({
 map: map,
 uri: "widgets/plotAttr/widget.js",
 name: "属性编辑",
 graphic: graphic,
 lonlats: graphic.coordinates
 })
 }
 }
function stopEditing() {
 timeTik = setTimeout(function () {
 es5widget.disable("widgets/plotAttr/widget.js")
 }, 200)
 }
```

### Initialize Mars2D Map and UI

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/example/graphic/basis/image-canvas/index.html

Sets up the Mars2D map, fits it to specified bounds, and changes the cursor style for the map container. Ensure the Leaflet library is loaded.

```javascript
"use strict";
// 开发环境建议开启严格模式
var map

function initUI() {
    map.fitBounds(L.latLngBounds([0, 70], [60, 140]))
    $(".leaflet-container").css("cursor", "crosshair")
}
```

### KML to GeoJSON Conversion (XML Document)

Source: https://github.com/marsgis/mars2d-es5-example/blob/master/lib/geojson/README.md

Converts KML data from an XML document object to GeoJSON format. This example uses jQuery's AJAX to fetch the KML content.

```javascript
//加载kml文档对象
$.ajax('https://data.mars2d.cn/file/kml/dg8.kml').done(function (xml) {
  kgUtil.toGeoJSON(xml).then((geojoson) => {
    console.log(geojoson)
  })
})
```
