Question

我的范围滑块工作正常，但在范围中显示所选范围。除了span，我想要在输入隐藏字段中打印范围，但不能这样做。

我提供了脚本，用 span 打印范围。

$(window).load(function(){
var range = $('.input-range'),
  value = $('.range-value');
  
value.html(range.attr('value'));

range.on('input', function(){
  value.html(this.value);
});

 
});//]]>

Answer 1

看看这段代码。它将当前值分配给隐藏字段。您可以通过单击按钮来检查当前值。

$(window).load(function(){
  var range = $('.input-range'),
  value = $('.range-value');
  
  value.html(range.attr('value'));

  range.on('input', function(){
    value.html(this.value);
    
    // Write value to hidden field
    $("input.test").val(this.value);
  });
  
  // Show current hidden input value
  $("#showValueButton").click(function() {
    var currentVal = $("input.test").val();
    alert("Current hidden input value: " + currentVal);
  });

 
});//]]>
