我正在尝试在我的代码中添加一个签名板,但是因为这是启动一个div元素并将scribble区域放入其中。我很震惊。 http://www.zetakey.com/codesample-signature.php
<script>
<div id="canvas"></div>
function signature() {
signatureCapture();
var canvas = document.getElementById("newSignature");
var dataURL = canvas.toDataURL("image/png");
alert(dataURL);
}
</script>
那么如何直接在视野中启动 提前谢谢。

我不确定我是否能够正确使用,但是可以选择使用您提供的库。
我建议您使用sap.ui.core.HTML组件添加将实例化签名板的相关html代码。为此,您需要在项目中使用Signature.js文件(从站点下载),并进行微小的更改。
请检查代码示例。
<强>的index.html 强>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta http-equiv='Content-Type' content='text/html;charset=UTF-8' />
<script src="resources/sap-ui-core.js" id="sap-ui-bootstrap"
data-sap-ui-libs="sap.m"
data-sap-ui-theme="sap_goldreflection">
</script>
<script>
sap.ui.localResources("util");
sap.ui.localResources("test");
jQuery.sap.require("util.Signature");
var view = sap.ui.view({id:"idApp1", viewName:"teste.App", type:sap.ui.core.mvc.ViewType.JS});
view.placeAt("content");
</script>
</head>
<body class="sapUiBody" role="application">
<div id="content"></div>
</body>
</html>
<强>测试/ App.view.js 强>
sap.ui.jsview("test.App", {
/** Specifies the Controller belonging to this View.
* In the case that it is not implemented, or that "null" is returned, this View does not have a Controller.
* @memberOf teste.App
*/
getControllerName : function() {
return "test.App";
},
/** Is initially called once after the Controller has been instantiated. It is the place where the UI is constructed.
* Since the Controller is given to this method, its event handlers can be attached right away.
* @memberOf test.App
*/
createContent : function(oController) {
var mySignature = '<div id="wrapper"> ' +
' <p>Zetakey Signature Webapp</p> ' +
' <div id="canvas"> ' +
' Canvas is not supported. ' +
' </div> ' +
' ' +
' <script> ' +
' signatureCapture(); ' +
' </script> ' +
' </div>';
var myhtml = new sap.ui.core.HTML();
myhtml.setContent(mySignature);
var clearBtn = new sap.m.Button({text: "Clear Signature", tap: function(evt) {
signatureClear();
}});
return new sap.m.Page({
title: "Title",
content: [
myhtml,
clearBtn
]
});
},
});
util / Signature.js (已下载,但我添加了第一行,使其成为ui5模块)
jQuery.sap.declare("util.Signature");

这对你有用吗? 让我知道。
问候。

实际上,我已经为此创建了一个签名板控件。这样您就可以将签名板代码封装在一个控件中。 http://jsbin.com/suquki/18/edit
