如何在 dojo 对话框中定位按钮？

Question

我在 javascript 和道场。基于我的关于非底层对话框的内容，我创建了一个对话框。现在我想将我的按钮添加到对话框中。该按钮是 dojo 按钮，它们都在 .我怎样才能在我的对话框中找到这些？

require(["dijit/Dialog", "dijit/DialogUnderlay", "dojo/domReady!"], function(Dialog, DialogUnderlay){
    //just for the snippets to get the right styling
    document.body.className = "tundra";




    myDialog2 = new Dialog({
        title: "My Dialog",
        content: "Test content.",
        style: "width: 300px"
    });

    showDialog2 = function () {
       myDialog2.show().then(function() {
            DialogUnderlay.hide()
            //little hack to avoid JS error when closing the dialog
            DialogUnderlay._singleton.bgIframe = {destroy: function() {}} 
       });
    }

});

<button onclick="showDialog2();">show without underlay</button>

<div id="navtool" >


      <div data-dojo-type="dijit/form/Button" id="zoomin"  >Zoom In</div>
      <div data-dojo-type="dijit/form/Button" id="zoomout" >Zoom Out</div>
      <div data-dojo-type="dijit/form/Button" id="zoomfullext" >Full Extent</div>
      <div data-dojo-type="dijit/form/Button" id="zoomprev" >Prev Extent</div>
      <div data-dojo-type="dijit/form/Button" id="zoomnext" >Next Extent</div>
      <div data-dojo-type="dijit/form/Button" id="pan" >Pan</div>
      <div data-dojo-type="dijit/form/Button" id="deactivate" >Deactivate</div>

     </div>

Answer 1

最简单的方法似乎是像这样编写 html-代码：

 var setContent = "<div data-dojo-type="dijit/form/Button" id="zoomin"  >Zoom In</div>";
                setContent += "<div data-dojo-type="dijit/form/Button" id="zoomout" >Zoom Out</div>";
                setContent += "<div data-dojo-type="dijit/form/Button" id="zoomfullext" >Full Extent</div>";

在定义对话框之前，然后使用您的变量设置对话框的内容，如下所示：

  myDialog2 = new Dialog({
    title: "My Dialog",
    content: setContent ,
    style: "width: 300px"
});

Answer 2

如果您给 dialog 的 content 属性一个 domNode，dojo 将为您放置节点并启动小部件。

require(["dijit/Dialog", "dijit/DialogUnderlay", "dojo/dom", "dojo/domReady!"], function(Dialog, DialogUnderlay, dom){
    //just for the snippets to get the right styling
    document.body.className = "tundra";
  

  
    myDialog2 = new Dialog({
        title: "My Dialog",
        content: dom.byId('navtool'),
        style: "width: 300px"
    });
  
    showDialog2 = function () {
       myDialog2.show().then(function() {
            DialogUnderlay.hide()
            //little hack to avoid JS error when closing the dialog
            DialogUnderlay._singleton.bgIframe = {destroy: function() {}} 
       });
    }

});
