Javascript不能在require php文件中使用Class "content"AdminL

我有2页chemical_data.php和chemical_selectAll.php。我将测试alert()点击按钮，但按钮id = "test1"不显示alert('1')

chemical_data.php

    <script>
        $(document).ready( function() {
             $('#OutputALLResult').load('chemical_selectAll.php');
             $('#test').click(function(){
                alert('1');  
             });
        }); 
    </script>
    <!-- Main content -->
    <section class="content">
    <div class="col-md-12">
         <div id="OutputResult"></div>
    </div>
    <hr>
        <button class="btn btn-default" type="button" id="test">testClick</button>
        <div id="OutputALLResult">Empty Data</div>
    </section>

chemical_selectAll.php

<script>
    $(document).ready( function() {
            $('#test1').click(function(){
            alert('1');  
            });
    });    
</script>
<button class="btn btn-default" type="button" id="test1">test1</button>
