原来脚本可以从主干视图访问。问题在于插件尝试访问窗口对象的方式。我使用了不同的脚本,效果很好。这就是我用的:
上传者.js
function my_uploader(evt) {
var files = evt.target.files; // FileList object
// Loop through the FileList and render image files as thumbnails.
for (var i = 0, f; f = files[i]; i++) {
// Only process image files.
if (!f.type.match('image.*')) {
continue;
}
var reader = new FileReader();
// Closure to capture the file information.
reader.onload = (function(theFile) {
return function(e) {
// Render thumbnail.
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="', e.target.result,
'" title="', escape(theFile.name), '"/>'].join('');
document.getElementById('list').insertBefore(span, null);
};
})(f);
// Read in the image file as a data URL.
reader.readAsDataURL(f);
}
}
主干视图脚本
events: {
"change #signageUploadInput": "loadImage",
},
loadImage: function(evt) {
my_uploader(evt); //script is inside fileuploader.js
}
