summernote基于Bootstrap的富文本编辑器，里面的上传图片处理。

话不多少，直接上干货。

  

function summernote() {
    $('.summernote').summernote({
        height: 200,
        onImageUpload: function(files, editor, welEditable) {
            sendFile(files[0], editor, welEditable);
        }
    });
};

function sendFile(file, editor, welEditable) {
    data = new FormData();
    data.append("file", file);
    $.ajax({
        data: data,
        type: "POST",
        url: "/upload/insert",
        cache: false,
        contentType: false,
        processData: false,
        success: function(url) {
            alert(url);
            editor.insertImage(welEditable, url);
        }
    });
}
