在您的 html 中:

In your html:

<canvas id="myCanvas" width="165px" height="145px"></canvas>

然后在 onDeviceReady 中:

function onDeviceReady()
{
    var canvas2ImagePlugin = window.plugins.canvas2ImagePlugin;
}

然后在保存画布的函数中:

then in the function to save your canvas:

// where myCanvasId == 'myCanvas' (the id of the canvas above)
function mySavingFunction(myCanvasId) {
    canvas2ImagePlugin.saveImageDataToLibrary(
        function(msg){
            console.log(msg);
        }, 
        function(err){
            console.log(err);
        }, 
        myCanvasId
    );
