JS計算器在wordpress中不起作用，腳本在舊站點上起作用

[英]JS Calculator not working in wordpress, script worked on old site

 原文  2018-09-27 15:57:18  4   1    javascript/ wordpress

問題描述

這個問題本周有問題。 我們正在創建一個新站點，因為當前站點有些過時了。 當前站點上有一系列可以完美運行的財務計算器。

將腳本和內容傳輸到新的wordpress網站后，我們收到一個錯誤，使其無法正常工作。

我們得到的錯誤是： 

    TypeError: document.formc is undefined[Learn More] accounting-calc.js:7:3
