怎么在前端获取checkbox的数据，然后传值去后端处理呀 这个是使用document，没有接触过

Answer 1

前端获取值的话可以这样
var str=document.getElementsByName("doc");
var chestr="";
for (i=0;i<str.length;i++)
{
if(str[i].checked == true)
{
chestr+=str[i].value+",";
}
}

后端的话 可以通过 String[] checkboxs = request.getParameterValues("doc"); 获取,然后对值进行处理 可参考https://blog.csdn.net/jungeCSND/article/details/123252835?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522165933891616780366569454%2522%252C%2522scm%2522%253A%252220140713.130102334.pc%255Fblog.%2522%257D&request_id=165933891616780366569454&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~blog~first_rank_ecpm_v1~rank_v31_ecpm-2-123252835-null-null.nonecase&utm_term=checkbox&spm=1018.2226.3001.4450
