组合两个数组，一个作为键，另一个作为值

Question

I have two arrays.

dat=['name','value','sub','mark']

dat1=[['mmm','lll','jjj','99'],['ccc','ccc','vvv','55']];

I need an like this

 $scope.alldata = [{name : mmm, value : lll, sub:jjj, mark :99}, {name : ccc, value : ccc, sub:vvv, mark :55}]

In php we can do it with array_combine. But I need it in angular js. Please help me..

Answer 1

You could use Array#forEach() and an object for populating the result.

 var dat = ['name', 'value', 'sub', 'mark'], dat1 = [['mmm', 'lll', 'jjj', '99'], ['ccc', 'ccc', 'vvv', '55']], result = dat1.map(function (a) { var o = {}; dat.forEach(function (k, i) { o[k] = a[i]; }) return o; }); console.log(result); 

Answer 2

Use Array#reduce in the callback of Array#map

 var dat = ['name', 'value', 'sub', 'mark'], dat1 = [ ['mmm', 'lll', 'jjj', '99'], ['ccc', 'ccc', 'vvv', '55'] ], op = dat1.map(function(item) { return item.reduce(function(a, b, index) { a[dat[index]] = item[index]; return a; }, {}) }); console.log(op);
