如何获得jQuery的变量的值

Question

jQuery代码：

<script> 
    $(document).ready(function() { 
     var ma = $("#qty").val(); 
     var str = $("#reqid").val(); 
     $("#myform").validate({ 
      rules: { 
       issue_quant_str: { 
        max: ma 
       } 
      } 
     }); 
    });​ 
</script> 

HTML：

<table> 
    <tr><td><?php echo $array['item_name']; ?></td> 
    <td><?php echo $array['quantity']; ?></td> 
    <input type="hidden" value="<?php echo $array['requisition_id']; ?>" id="reqid" /> 
    <td> 
     <div id="maxdiv"> 
      <input type="text" name="issue_quant_<?php echo $array ['requisition_id'];?>" value="<?php echo $array['quantity']; ?>" /> 
     </div> 
    </td> 
    <input type="hidden" value="<?php echo $stock_qty; ?>" id="qty" /> 
    <td><?php echo $stock_qty;?></td> 
    <td><input type="text" name="rem_<?php echo $array['requisition_id'];?>" required/></td> 
</tr> 
</table> 

在这里，我想与issue_quant.I串接VAR海峡价值无法得到海峡value.Can谁能帮我..

Answer 1

尝试var str=$("#reqid").text();

前提是你的reqid住在你的HTML代码和具有内

Answer 2

var rules = {}; 
rules['issue_quant_' + str] = {max:ma}; 
$("#myform").validate({ 
    rules: rules 
});
