1.页面：(1)js传参数：location.href="${ctx }/forum/changeCtm.html?ctmId="+id;
(2)将内容写在form表单里面，然后用表单提交
<form method="post" action="${ctx }/forum/savePost.html" name="form1"> <input type="hidden" name="postId" value="${postId }"> <input type="hidden" name="postType" value="${forumPost.postType }" id="postType"> <input type="hidden" name="plateName" value="${forumPost.plateName }" id="plateName"> <a href="javascript:void(0);" class="comBtn" onclick="submitForm1(this);">提交</a> </form>
如果需要验证表单，可以在js里面验证之后，然后用 "表单名".submit();来提交
function submitForm1(src){
//………………
form1.submit();
}
也可以修改表单提交的action，然后再提交。此方法可实现在同一表单内，点击不同按钮，跳转的不同的action
form1.action="${ctx }/forum/savePostReFeedback.html?postReId="+id ;
form1.submit();
后台：可以有三种方法获取
(1)@RequestMapping(value="/changeCtm")
public String changeCtm(Model model,HttpServletRequest request,Long ctmId){}
直接在方法里面写参数名
(2)@RequestMapping(value="/changeCtm")
public String changeCtm(Model model,HttpServletRequest request,Customer customer){}
Customer里面有属性，ctmId
(3)@RequestMapping(value="/changeCtm")
public String changeCtm(Model model,HttpServletRequest request){
Long ctmId = request.getParameter("ctmId");
}
参数列表里面不用写，在方法体内通过原始方法获取
2.用json实现与后台交互
(1)前台：将参数写进链接里面
$.post("${ctx}/forum/savePostVote-" + postId + "-"+flag+".json", null, function(result) {
result = eval("(" + result + ")");
if (result.status == "true" || result.status == true) {
alert(result.msg);
state=0;
} else {
alert(result.msg);
state=1;
}
});
后台，在映射的url里面配置对照的参数，然后在方法参数列表里面配置 处理requet uri 部分的注解PathVariable，与url参数对应即可
@RequestMapping(value="/savePostVote-{postId}-{flag}")
public ResponseEntity<String> savePostVote(Model model , HttpServletRequest request,@PathVariable(value = "postId") Long postId,@PathVariable(value = "flag") Integer flag){}
(2)前台：将参数写进params里面，传到后台
var params = { id : id }; $.post("${ctx}/admin/forum/deletePlate.json", params, function( result) { result = eval("(" + result + ")"); if (result.status == "true" || result.status == true) { alert(result.msg); window.location.reload(); }else{ alert(result.msg); } });
后台：将参数写在参数列表内
@RequestMapping(value = "/deletePlate") public ResponseEntity<String> deletePlate(Model model,HttpServletRequest request,String id) throws Exception {}
