Javascript 在数组中的对象上循环，显示来自JSON的数据 客观的

我希望在数组中循环对象，这样每个使用

html（）

的学校都可以从

schools.js中的数据中反映其名称、学区以及英语、数学、科学和社会研究的百分比

问题：现在，我只得到阵列中的最后一个学校

是否可以在没有数据id的情况下执行此操作？附属于每一所学校，或者这是确定哪所学校是哪所学校的实际必要条件

您必须在javascript中创建一些html模板，并在其中连接可更改的数据，并在每次更新时附加到父元素


var学校=[
{
“名称”：“学校1”，
“地区”：“地区1”，
“盾徽”：“，
“地点”：“，
“英语百分比”：“1%”，
“百分比数学”：“21%”，
“百分比科学”：“41%”，
“社会百分比”：“61%”
},
{
“名称”：“学校2”，
“地区”：“第2区”，
“盾徽”：“，
“地点”：“，
“英语百分比”：“2%”，
“百分比数学”：“22%”，
“百分比科学”：“42%”，
“社会百分比”：“62%”
}];
//生成从1到20的数字
for（var i=0；i”
)
}

您的javascript正在替换循环中每个学校相同元素中的HTML，这就是为什么您只看到最后一个学校。您需要为每个学校创建一组新的HTML元素（克隆和附加会有帮助），以防止覆盖以前的学校。
问题在于使用类选择器时，会选择许多元素。使用
.html（）
时，它不知道要针对哪个元素

您可以通过使用
.eq（）
通过索引将特定元素作为目标来轻松解决此问题
    // Generate numbers from 1 through 20
    for(var i = 0; i < schools.length; i++) {
        var schoolID = i + 1
        console.log(schoolID);

        // Schools
        var schoolName = $(".school__name").html(schools[schoolID].name); // Name
        var schoolDistrict = $(".school__district").html(schools[schoolID].district); // District
        // var schoolCrest = // $(".school__image").attr("src", schools[schoolID].crest) // Crest

        // Percentage
        var percentEnglish = $(".school__district").html(schools[schoolID].english); // English
        var percentMath = $(".school__district").html(schools[schoolID].math); // Math
        var percentScience = $(".school__district").html(schools[schoolID].science); // Science
        var percentSocial = $(".school__district").html(schools[schoolID].social); // Social Science
    }
