Question

我已尝试过此代码的每个变体，似乎没有任何工作。我想将一个搜索词提供给一个函数，并捕获API调用引发的任何错误。

错误如下：

GET insight.bitpay.com/block/afasfasf 404 (Not Found)
x.support.cors.e.crossDomain.send 
@ ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js:6x.extend.ajax 
@ ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js:6x.(anonymous function) 
@ ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js:6searchFunction 
@ (index):109(anonymous function) 
@ VM11642:2InjectedScript._evaluateOn 
@ VM11641:904InjectedScript._evaluateAndWrap 
@ VM11641:837InjectedScript.evaluate 
@ VM11641:693

代码：

＆＃13;

function searchFunction(category, searchTerm) {
  $.get("https://insight.bitpay.com/" + category + "/" + searchTerm,  function(data) {
    return data;
  }).fail(function() {
    return "fail";
  });
}

// --------------- Search bar --------------- //
$(document).ready(function() {
  $("#search-form").on("submit", function(e){
    e.preventDefault();
    var searchTerm = $("#srch-term").val();
    var searchBlockHash = searchFunction("block", searchTerm);
    if (searchBlockHash != "fail") {
      // some function(searchBlockHash)
    } else {
      // some error message
    }
  });
});

＆＃13;

<form id="search-form" class="navbar-form navbar-left">
  <div class="input-group input-group-sm" style="min-width:512px">
    <input type="text" class="form-control" placeholder="Search for a block, transaction or address" name="srch-term" id="srch-term">
  </div>
</form>

＆＃13;

Jquery get（）没有捕获错误
