Use val()instead of text()

使用val()代替text()

var hv = $('#h_v').val();
alert(hv);

You had these problems:

你有这些问题：

• Single quotes was not closed
• You were using text()for an input field
• You were echoing xrather than variable hv

• 单引号没有关闭
• 您text()用于输入字段
• 你是在回声x而不是变数hv

这应该有效：

alert(hv);

If you don't want to assign identifier to the hidden field; you can use name or class with selector like:

如果您不想为隐藏字段分配标识符；您可以将名称或类与选择器一起使用，例如：

$('input[name=hiddenfieldname]').val();

or with assigned class:

或指定班级：

$('input.hiddenfieldclass').val();

Closing the quotes in var hv = $('#h_v).text(); would help I guess

关闭引号 var hv = $('#h_v).text(); 会帮助我猜
