如何将readonly文本框值转换为javascript变量 [英] How to get the readonly textbox values into javascript variable

问题描述

我有一个表格里面使用php我填充文本框字段并将其设置为readonly.now我想将readonly文本框值变为javascript中的变量并进行验证。加载文档后我试图存储值变成变量我得到空字符串。这样可以做到这一点。请帮帮我。谢谢。



<前lang =HTML> < div class = col-md-1 >
< div 类 = form-group >
< label > CAPACITY < / label >
< 输入 type = text id = student1 名称 = student1 value = <？php echo $ venuecapacity1;？> readonly class = form-control >
< / div >
< / div >
< div class = col-md-1 >
< div class = form-group >
< label > 要分配< / label >
< 输入 < span class =code-attribute> type = text id = cpcty1 名称 = capacity1 class = form-control >
< 输入 type = hidden id = fld1 name = filled1 value = <？php echo $ capacity;？> readonly class = 表单控件 >
< / div >
< / div >
< / div >

我尝试过：

< pre> $（ document ）。ready（函数（）{
  debugger ; 
  var  aloted = $（  #fld1 ）VAL（）; 
  var  capacity = $（ ＃cpcty1 ）VAL（）; 
  var  aloted2 = $（  #fld2 ）VAL（）; 
  var  capacity2 = $（ ＃cpcty2 ）VAL（）; 
  var  aloted3 = $（  #fld3 ）VAL（）; 
  var  capacity3 = $（ ＃cpcty3 ）VAL（）; 
 
 $（ ＃cpcty1）。change（ function （）{
 
 alert（aloted）; 
 alert（capacity）; 
}）; 
}）; 
< / script>
