Question

我正在尝试获取div中的数字（由服务器生成），并相应地对div进行更改（所以基本上，如果数字> = 4，则进度条将变为绿色，标题为“ superb”，如果> = 3 < 4，橙色进度条，标题为“好”等。）

js：

var scores = $("div.progress-bar");
function progressbar_function(){
if (parseInt($(this).text()) >= 4){
$(this).addClass("bg-success");
$(this).text('Superb');
} else if(parseInt($(this).text()) >= 3) {
$(this).addClass("bg-warning");
$(this).text('Good');
}
};
$.each(scores, function(index, item) {
$(item).change(progressbar_function);
});

html

  <ul class="list-group festival-list">
                  <li class="list-group-item">
                    <span class="float-left"><span class="ec ec-banana"></span> Vegan friendly:</span>
                    <div class="progress float-right" style="width: 50%; height: 22px;">
                      <div class="progress-bar" role="progressbar" style="width: {% widthratio vegan_friendly_avg 5 100 %}%" aria-valuenow="{{vegan_friendly_avg|default_if_none:"No reviews yet"}}" aria-valuemin="0" aria-valuemax="5">{{vegan_friendly_avg|floatformat:2|default_if_none:"No reviews yet"}}</div>
                    </div>
                  </li>
                  <li class="list-group-item">
                    <span class="float-left"><span class="ec ec-coffee"></span> Coffea quality:</span>
                    <div class="progress float-right" style="width: 50%; height: 22px;">
                      <div class="progress-bar" role="progressbar" style="width: {% widthratio coffea_quality_avg 5 100 %}%" aria-valuenow="{{coffea_quality_avg|default_if_none:"No reviews yet"}}" aria-valuemin="0" aria-valuemax="5">{{coffea_quality_avg|floatformat:2|default_if_none:"No reviews yet"}}</div>
                    </div>
                  </li>
.

.
</ul>

它不起作用，我在做什么错？：（

尝试

CurrentDb.Execute "UPDATE [Table Name] SET Note = 'aaaa' WHERE [Codice Progetto] = 'XX';"

Answer 2

var scores = $("div.progress-bar");
function progressbar_function($item) {
    if (parseInt($item.text()) >= 4) {
        $item.addClass("bg-success");
        $item.text('Superb');
    } else if (parseInt($(this).text()) >= 3) {
        $item.addClass("bg-warning");
        $item.text('Good');
    }
};
$.each(scores, function (index, item) {
    progressbar_function($(item));
});

此代码应该起作用。您的代码的问题在于，没有div的have change事件不会触发任何change事件，因此应在加载脚本时初始化progressbar样式。

jQuery函数获取文本并相应地更改div样式
