آموزش clone یا نمونه سازی از تگ های html در جاوا اسکریپت

آموزش clone یا نمونه سازی از تگ های html در جاوا اسکریپت

clone از html با جاوا اسکریپت و کتابخانه jquery cloner ، با کمک این کتابخانه می توانیم خیلی راحت از تگ های html نمونه بگیریم .

این پروژه را در 2 سطح انجام می دهیم :

  1. نمونه عادی
  2. نمونه تو در تو



خروجی برنامه


در نمونه تو در تو از تقویم فارسی ، select2 و نمونه در نمونه استفاده می کنیم .

ویژگی که این پروژه دارد این است که در هر تغییر input های فرم از جمله select در hidden داده ها به صورت آرایه ذخیره می شود .

جزئیات dataset ها

  1. data-seperator : زمانی که بخواهیم اعداد را به صورت 3 رقم 3 رقم جدا کنیم از این ویژگی استفاده می کنیم
  2. data-value : این ویژگی مورد شماره 1 مرتبط است یا موارد مشابه در صورتی که بخواهیم مقدار 1,234 را به صورت 1234 ذخیره کنیم به کار مان می آید .
  3. data-optional : در صورتی که بخواهیم بگوییم این فیلد در لیست مان اختیاری است این dataset به کار مان می آید . دلیل آن این است که هر مقدار که در hidden ذخیره باشد و دارای مقدار null باشد فرم ناقص تلقی می شود با این ویژگی به جای null مقدار “” ذخیره می کنیم .
  4. data-empty : این ویژگی فقط برای فیلد هایی که کلاس data-field ذخیره می شود همان hidden که داده ها را به صورت آرایه ذخیره می کند و در صورتی که در آرایه فیلدی را کاربر کامل نکرده باشد این ویژگی ظاهر می شود .
