Question

嘿伙计们我在这里有一个jquery滑块的代码。我想取出滑块的值并使用http post方法将值提交给数据库。我有一个处理表单，我成功用于文本框和单选按钮。我希望将滑块的值保存在隐藏的字段中，然后发布它。我知道这从滑块获取值。

    var selection = $( ".selector" ).slider( "value" );

现在我如何将此添加到此提交表单中的值中？

    <input type='hidden' class="mainForm" id="fieldBox_5" name="field_5" value=selection>

这是我的全部代码。

Answer 1

我添加了额外的代码来将所选值（从下拉列表或滑块）复制到隐藏字段。诀窍是，一旦获得所选项目的值，您需要自己将其复制到隐藏字段。

相关更改在此处（我也将其打印到控制台以验证值，您可以在检查它为您正常工作后删除这两行）：

var selection = $("#slider").slider("value");
console.log("Slider value: " + selection);
$("#selectedNumber").val( selection );
console.log("Hidden field value: " + $("#selectedNumber").val());

请参阅以下演示：

$(function() {
    var select = $("#minbeds");
    var slider = $("<div id='slider'></div>").insertAfter(select).slider({
      min: 1,
      max: 10,
      range: "min",
      value: select[0].selectedIndex + 1,
      slide: function(event, ui) {
        select[0].selectedIndex = ui.value - 1;
        $("#selectedNumber").val( ui.value - 1 );
        console.log("Slider value: " + (ui.value - 1) );
        console.log("Hidden field value: " + $("#selectedNumber").val());              
      }
    });
  
    $("#minbeds").change(function() {
      slider.slider("value", this.selectedIndex + 1);
      var selection = $("#slider").slider("value");
      console.log("Slider value: " + selection);
      $("#selectedNumber").val( selection );
      console.log("Hidden field value: " + $("#selectedNumber").val());      
    });
  });

#slider {
  margin: 20px;
  width: 400px;
}

在你的最后一个JS代码之后（在准备好的块中）

document.getElementById('fieldBox_5').value = selection;或$('#fieldBox_5').val(selection);（如果你更喜欢jQuery）啊，你需要在on ready方法中移动var selection声明太

从Jquery滑块
