Question

HTML

$(document).on("click", "#bkash-radio", function() {
    console.log('test');
    $("#trx_id").attr("type", "text");
});

$(document).on("blur", "#bkash-radio", function() {
    console.log('test');
    $("#trx_id").attr("type", "hidden");
});

jQuery函数：

to_csv

我试图在选择第二个单选选项时显示文本框id = trx_id，但是当取消选择它时，我希望隐藏文本框。我怎么能这样做？

点击change活动，看看this.value==="2"
分别操纵prop 类型

$(document).on("change", "[name='payment_options']", function() {
  $("#trx_id").prop("type", this.value==="2" ? "text" : "hidden");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-default active">
    <input type="radio" name="payment_options" value=1 autocomplete="off" checked>Cash on Delivery
  </label>
  <label class="btn btn-default" id="bkash-radio">
    <input type="radio" name="payment_options" value=2 autocomplete="off">bKash
  </label>
</div>

<input type="hidden" name="trx_id" id="trx_id" class="form-control" placeholder="Enter Transaction ID"/>
