js合并两个数组生成合并后的key：value数组

核心代码

// var activesubjectsname = ["语文", "数学", "英语", "思想品德", "科学"];
// var activesubjectsnum = [46, 2, 2, 28, 29];
// var activesubjectsarr = [];

for (var i = 0; i < activesubjectsname.length; i++) {
 console.log(i);
 var activesubjectsobject = {};
 for (var j = 0; j < activesubjectsnum.length; j++) {
  if (i == j) {
   activesubjectsobject.name = activesubjectsname[i];
   activesubjectsobject.value = activesubjectsnum[j];
   activesubjectsarr.push(activesubjectsobject);
  }
 }
}
console.log(activesubjectsarr);
// activesubjectsarr=[
// {name: "语文", value: 46},
// {name: "数学", value: 2},
// {name: "英语", value: 2},
// {name: "思想品德", value: 28},
// {name: "科学", value: 29}
// ]

原理就是将两个数组结合到一个数组里面，跟json对照关系一样，需要的朋友可以参考一下，注意两个数组按顺序对应好即可。
