我有一個滑塊和一個下拉菜單。每當有人使用下拉菜單我想滑塊設置回2014年的位置。我不知道如何在JavaScript中做到這一點。在腳本下面,我添加了我認爲它應該與該行一致的地方。有沒有人有腳本下的想法?將滑塊設置爲標準位置Javascript

啊,你是荷蘭或比利時(我是比利時)

這是短一點,比你想象得容易。沒有開關需要那裏(除非你需要如果其他的東西?然後把它放回去)

<script> 
$(function() { 
    $("#lplist").on("change", function(e) { 
    var value = e.currentTarget.value; 
    // we don't need the value; just the index. 
    // we read the index and set that index to the silder 
    var index = $("#lplist").index(e.currentTarget) ; // looks for what position the option has within the select 
    slider.setIndex(index); 
    }); 

    var select = $("#Jaartal"); 
    var slider = $("<div id='slider'></div>").insertAfter(select).slider({ 
    min: 1, 
    max: 8, 
    range: "min", 
    value: select[ 0 ].selectedIndex + 1, 
    slide: function(event, ui) { 
     var index = ui.value-1; 
     select[0].selectedIndex = index; 
     if (select[0][index].text === "2014") { 
     } 
     if (select[0][index].text === "2015") { 
     } 
     if (select[0][index].text === "2016") { 
     } 
     if (select[0][index].text === "2017") { 
     } 
     if (select[0][index].text === "2018") { 
     } 
     if (select[0][index].text === "2019") { 
     } 
     if (select[0][index].text === "2020") { 
     } 
     if (select[0][index].text === "2025") { 
     } 
    } 
    }); 
    $("#Jaartal").change(function() { 
    slider.slider("value", this.selectedIndex + 1); 
    }); 
}); 
</script>

我需要開關的其他原因。其實我想在每次切換時都激活它。我試圖在交換機中實現你的代碼,但不幸的是它似乎不工作。我試圖讓索引成爲一個全局變量,但這也沒有成功。 – Zuenie 2015-03-04 07:54:18

O,對不起。你只需要滑塊回到2014年。沒有其他價值?我會修改劇本。 – 2015-03-04 09:34:21

不要對不起。你幫助我!非常感謝您繼續提供幫助。期待劇本,這是一個令人討厭的複雜情況。 – Zuenie 2015-03-04 09:50:01
