jSignature 因缺少导入插件而失败

Question

Calling jSignature with

var hiddenSignature = $('#signature' + i).jSignature();
hiddenSignature.jSignature('setData', 'base30' + signatureContentBase30);

gives this error

jSignature.min.js:57 Uncaught Error: jSignature is unable to find import plugin with for format 'undefined'
    at r.fn.init.f (jSignature.min.js:57)
    at r.fn.init.$.fn.(formso365.nintex.com/Pages/anonymous function) [as jSignature] (https://progressivehomecare.sharepoint.com/sites/intakeworkflow-dev/SiteAssets/ScriptLibraries/jSignature.min.js:61:18)

    at init.ready (jquery-1.10.2.min.js:4)
    at registerSignatureFields.js:14

Using this code

var hiddenSignature = $('#signature' + i).jSignature();
hiddenSignature.jSignature('setData', 'data:image/jsignature;base30,' + signatureContentBase30);

I get the error

jSignature.min.js:65 Uncaught TypeError: Cannot read property 'split' of undefined

I don't know what to try and this is my first time with jSignature (taking over from someone else)

Answer 1

Assuming you are talking about http://www.unbolt.net/jSignature/

Use

$('#signature').jSignature('getData', 'default')

This will create something like:
