Question

Jsp代码从表中的一行获取。

<li><a href="otherpageJsp?idParam1=${value1}&idParam2=${value2}"
      onclick="otherpageJsp"</a></li>

在模型和视图中

@RequestMapping(value = "otherpageJsp")
public ModelAndView goPage(@RequestParam String idParam1,String idParam2, Model model) {
    ModelAndView mav = new ModelAndView("otherpageJsp");
    mav.addObject("current", "otherpageJsp");
    mav.addObject("value1", idParam1);
    mav.addObject("value2", idParam2);
    return mav

当onclick()被调用时，我只得到value1，value2 = null。有人可以帮我解决吗？

Answer 1

只需添加document.getElementById("guess").onclick=function() { if(document.getElementById("myNumber").value > 5) { document.getElementById("myNumber").value = ""; alert("Please provide a number that is with in 0 to 5"); } else { var gotit=false; var guesses=1; var x; while(gotit==false) { x=Math.random(); x=6*x; x=Math.floor(x); if(document.getElementById("myNumber").value==x) { gotit=true; } else { guesses++; } } alert("Got it! It was a " + x + ". It only took me " + guesses + " guesses!"); }即可将参数值设置为方法参数。

<script language="javascript">
var timeout;
function open_webapp() {
    window.location='https://oursite.com/path/to/destination';
}

function try_to_open_app() {
    timeout = setTimeout('open_webapp()', 300);
}
</script>
<a onClick="javascript:try_to_open_app();" href="yourappurl:">App    name</a>

Answer 2

在URL查询字符串中发送参数时，最好使用QueryParam。试试这个：

public ModelAndView goPage(@QueryParam("idParam1") String idParam1, @QueryParam("idParam2") String idParam2, Model model) {

Answer 3

你可以试试这个

@RequestMapping(value = "otherpageJsp", method=RequestMethod.GET)
public ModelAndView goPage(@RequestParam("idParam1") String idParam1, @RequestParam("idParam2") String idParam2, Model model) {
    ModelAndView mav = new ModelAndView("otherpageJsp");
    mav.addObject("current", "otherpageJsp");
    mav.addObject("value1", idParam1);
    mav.addObject("value2", idParam2);
    return mav
}

Answer 4

对我有用。我将jst用于href

HTML

<c:url var="addNewDistribution" value="/credit/showFormforAddDistribution">
    <c:param name="credit"  value="${creditNumber}" />
    <c:param name="work"    value="${creditNumber}" />
</c:url>                    
<a href="${addNewDistribution}">add</a>

模型视图

@GetMapping("/showFormforAddDistribution")
public String showFormforAddDistribution(@RequestParam String credit,@RequestParam String work, Model theModel) {}

如何在href中获取2个参数 - Spring MVC？
