Question

在角度方面，我有一个对象：

$scope.myobj = {
"a":"",
"b":"",
"c":""
}

我希望能够在文本框输入上使用ng-repeat和ng-model，以便在文本框中输入将更新“a”，“b”和“c”。现在我的HTML是：

<div ng-repeat="(keyname, keyvalue) in myobj">
  <input ng-model="keyvalue" value="{{keyvalue}}">
</div>

Answer 1

你可以试试这个，

   <div ng-repeat="(keyname, keyvalue) in myobj">
     <input ng-model="myobj[keyname]" >
   </div>

＆＃13;

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.myobj = {
"a":"",
"b":"",
"c":""
}
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<div ng-repeat="(keyname, keyvalue) in myobj">
  <input ng-model="myobj[keyname]" >
</div>
 OBJECT VALUES :  {{myobj}}
</div>

Answer 2

你可能需要改变一下你的obj。制作数组（运行代码段）

# Put a wedge between "prefix" and "date.CSV" part.
# We don't salvage the .csv extension, that drops off here.
# Note the space padding before/after \1, we'll use that shortly.
s/([0-9_]+)\.csv/ \1 /g
#    in:  "abc1_bbb_yyy_2_8_15.csv"
#    out: "abc1_bbb_yyy _2_8_15 "
# (If I knew how to do non-greedy matching in sed we could
# strip the prefix e.g. "abc1_bb_yyy" part here as well,
# but if we try that we end up with just "_15 ", e.g. our
# other month & day get eaten).
# Hence sacrificial space character that our
# next substitution will use to cut the prefix.

# Cut the prefix.
# strip up to, but not including, the first non-space char.
# (I don't think you can do non-greedy matching in sed).

s/^.* ([^ ])/\1/
#    in:  "abc1_bbb_yyy _2_8_15 "
#    out:              "_2_8_15 "

# change our underscores to two space chars.
# (turns out we need two intermediate spaces for
# the next substitution to work as a single "global" substitution)
s/_/  /g
#    in:   "_2_8_15 "
#    out:  "  2  8  15 "
# At this point all of our month/day/year parts 
# have *two* spaces between them.

# Next we do zero-padding if necessary.
s/ ([0-9]) / 0\1 /g
# Important: we're looking for a single space before
# and after any single digit.
#    in:  "  2  8  15 "
#   out:  " 02 08  15 "
# input broken out by single chars with "spc"= 1 space char.
#         +---+---+---+---+---+---+---+---+---+---+---+
# input:  |spc|spc| 2 |spc|spc| 8 |spc|spc| 1 | 5 |spc|
#         +---+---+---+---+---+---+---+---+---+---+---+
#              \         / \         /     no match, not
#               \       /   \       /      a single digit.
#                \     /     \     /
#                match 1     match 2
#               /       \   /       \
#              /         \ /         \
#         +---+---+---+---+---+---+---+---+---+---+---+
# result  |spc| 0 | 2 |spc| 0 | 8 |spc|spc| 1 | 5 |spc|
#         +---+---+---+---+---+---+---+---+---+---+---+
# Without "two spaces" between digits this
# would require 3 separate substitutions...
# doing a single global e.g. s/ ([0-9]) / 0\1 /

# Pretty much done, just strip the spaces.
s/ //g
#   in:   " 02 08  15 "
#   out:  "020815"

(function ()
{
    var app = angular.module("app", []);

    function HomeController()
    {
        var vm = this;
        vm.myobj = [{"name":"a"},{"name":"b"},{"name":"c"}];

    }

    app.controller("HomeController", [HomeController]);

})();

使用keyname而不是keyvalue。也为您的数组键赋予一些价值。然后尝试使用keyvalue。它肯定会起作用
