我用一些代码创建了文本对象，如：
var surface = dojox.gfx.createSurface(dojo.byId("gfx-holder"), 850, 400);
var myText = surface.createText({x:55, y:60, text:"Original"});
稍后我想更改文本。我已经尝试了很多变化：
myText.text = "Updated";
或
myText.setText({text: "Updated"});
运气不好，我想用更新的文本替换原始文本。删除旧的并重新绘制的唯一选择吗？
您可以简单地访问该节点并更改它的innerHtml文本，如
myText.rawNode.innerHTML = "Updated !";
请参见以下代码段：
require([ "dojo/dom", "dijit/registry", "dojo/_base/lang", "dojo/ready", "dojox/gfx", "dijit/ConfirmDialog", "dijit/form/Button"],
function( dom, registry, lang, ready, gfx) {
let i = 0;
ready(function() {
var surface = gfx.createSurface(dom.byId("gfx-holder"), 200, 100);
var myText = surface.createText({x:55, y:60, text:"Original"});
registry.byId("btn").on("click", function(e) {
i++;
myText.rawNode.innerHTML = "Updated !"+i;
});
})
}
);#gfx-holder {
border: 1px solid black;
}
#gfx-holder {
fill-opacity: 1 !important;
}
#gfx-holder text {
fill: black !important;
fill-opacity : 1 !important;
