表格应仅在填写所有数据时提交 [英] Form should submit only when all data is filled
问题描述
我现在正在创建从我们的校园取出材料的材料旁路。
在第一页中，输入人员姓名取出材料，issue_date，department，vehicle_no，driver_name，purpose，received_by和remarks 。
在第二页没有。给出的材料。
在第三页，它创建没有。第二页中提到的行。假设5.创建了五行。此页面中的字段为material_name，company_sr_no，department_sr_no，数量，重量，备注。有两个按钮。一个是'取消''，另一个是表单提交按钮''添加''。
这里在第三页，常常出现一个问题。如果错误地按下回车键而没有填写所有细节，则提交表格（即按下添加按钮）。我怎么能阻止这个？我想在没有填充所有五行的情况下应该没有输入键的效果。如果任何人试图点击添加，添加按钮不应该工作，除非所有五行材料都被填满。
谢谢和问候，
Vikas

Here in third page, one problem regular occurs. When enter key is pressed by mistake without filling all details, the form is submitted (i.e. ''Add'' button is pressed). How can I stop this? I want to there should be no effect of enter key without filling all the five row. If any one tries to click ''Add'', ''Add'' button should not work untill and unless all the five rows of material are filled.
Thanks and regards,
Vikas
