Question

我想使用JavaScript使用JSON文件中的数据验证表单输入。目的是确保用户输入与JSON文件中的信息匹配的正确clnt_key数据。我该怎么办？

<form>

  <div class="form-group">
    <input type="text" class="form-control" id="text1" aria-describedby="emailHelp" placeholder="Enter Client key">
  </div>

  <button type="button" onclick="javascript:validate()" class="btn btn-danger btn">Login</button>

</form>

这是似乎无法正常运行的JavaScript代码。

<script>
  function validate() {

    $.getJSON("clientkey.json", function(data) {


      $.each(data.response.message.org_details, function(key, value) {

        if (document.getElementById("text1").value == "CLNT_KEY") {
          alert("validation succeeded");
          location.href = "login.html";
        } else {
          alert("validation failed");
          location.href = "fail.html";
        }

      });

    });
  }
</script>

这是我的JSON文件

{
  "response": "yes",
  "message": "Client Key Exists",
  "org_details": {
    "ENTY_ID": 31,
    "ORG_LGL_NME": "Patterson Park Neighborhood Association",
    "ORG_NME": "Patterson Park Neighborhood Association",
    "ORG_DESC": null,
    "CLNT_KEY": "PPNA2017",
    "ADMN_KEY": "appna2017",
    "FED_TAX_ID": null,
    "ORG_INDST_CD": 20,
    "ORG_ANNL_REVN_AMT": null,
    "ORG_INCORP_CNTRY_CD": 840
  }
}

应该是：

$.each(data.response.message.org_details, function(key, value){

    if (key === "CLNT_KEY" && document.getElementById("text1").value === value)
    {
        alert( "validation succeeded" );
        location.href="login.html";
    }
    else
    {
        alert( "validation failed" );
        location.href="fail.html";
    }

});
