如果此href包含var

Question

Trying to check if href contains a var. No luck so far

  var navcur = window.location.href;
  $(".subnavli").each(function(){
    if ($(this).find("a[href=" + navcur + "]")) {alert('works!');}  
  });

Answer 1

Since the href have special chars you need to wrap the attribute value. Also .find() returns a jQuery object irrespective of whether a match is found or not so you need to check whether the jQuery object contains any elements - you can check the length property for that

var navcur = window.location.href;
$(".subnavli").each(function () {
    if ($(this).find("a[href='" + navcur + "']").length) {
        alert('works!');
    }
});

It can be simplified using descendant selector instead of using a loop

var navcur = window.location.href;
var $a = $(".subnavli a[href='" + navcur + "']");
if ($a.length) {
    alert('works!');
}

Answer 2

this works for me:

 var navcur = window.location.href

 $(".subnavli").each(function(){      
   if ($(this).attr("href") ===navcur) {alert('works!');}  
 });
