javascript - <form>里button,submit,reset 包括<form>自己 name 属性是不是都没有用?
我是零散着学习的,也没做过项目,就是每学一个对象,一个函数,我就做做实验,有联系的东西,我就把类似的往上套
我知道
<code><input type="text" name="" value="" class=""> <input type="radio" checked name="" value="" class=""> <input type="checkbox" checked name="" value="" class=""></code>
中的name确实是有用的,可以给 PHP 传值,但是
<code><form name="★" action="shiyan-1.php" method="get"> <input type="button" id="" class="" name="" value="显示名"> <input type="submit" id="" class="" name="" value="提交"> <input type="reset" id="" class="" name="" value="清空"> </form></code>
中的name属性,除了在JavaScript用 document.getElementsByName("")[0] 和用 jQuery 的$("[name='']") 获取节点之外,是不是就没有其他用处了?
以后只要我不用js,那我就不用写 name 属性了是吗?
还有就是这个
<code><input type="radio" checked name="" value="" class=" "> <input type="radio" checked name="" value="" class=""></code>
中的 value 有什么用?他们不就是个 布尔值 吗,选上是true,选不上false?用 checked 就能判定了,为什么还有个 value ,这个怎么传给服务器?

当按钮的type="submit", 有name时, 并且method="get", 是会提交的, type="button | reset"不管有没有name都不会
2.type="radio"的value是传个后端的, checked只能js来判断, 只要有name, 自然就会把选择的value传给后端
你这一看就是新手啊 !
