how to dynamically add REQUIRED attribute to textarea tag using jquery?
提问by Rohit
I tried adding REQUIRED
attribute using .attr("required","true");
but its not making text area compulsory. Do not want to make all textarea
, compulsory, hence trying to do it dynamically.
我尝试添加REQUIRED
属性 using.attr("required","true");
但它不强制文本区域。不想使 all 成为textarea
强制性的,因此尝试动态地进行。
