将参数传递给<；html:link>；来自javascript DEMO

如何从javascript传递val1和val2？

将

styleId=“myLink”

添加到

以使用javascript查询元素。
然后可以在JS中执行以下操作：

<html:link href="DemoAction.do?method=val1&param1=val2">DEMO</html:link>

var val1 = "newval1", val2 = "newval2";

// Option 1: Set the href attribute regardless of its current value
var link = document.getElementById("myLink");
link.setAttribute("href", "DemoAction.do?method="+val1+"&param1="+val2);

// Option 2: Set the href attribute depending on its current value
var link = document.getElementById("myLink"),
    hrefParts = link.getAttribute("href").split("?");
link.setAttribute("href", hrefParts[0]+"?method="+val1+"&param1="+val2);
