Question

我使用角度，当选中复选框时，我想更改数据字段指令/标记的值。

<tbody data-ng-repeat="(contractIndex,contract) in contracts">
  <tr>
    <td>
      <div id="suppliername" data-strat-form-control data-field-display-id="1" data-vmformreadonly="true" data-show-tool-tip="showToolTip(contract.fields[4].htmlName)" data-strat-model="contract" data-field="(contract.hasOwnProperty('COMMIT_CONTRACT')) ? contract.fields[5] : contract.fields[4]"></div>
    </td>
    <td class="text-center">
      <div data-strat-form-control data-field-display-id="20" data-vmformreadonly="formReadOnly" data-show-tool-tip="showToolTip(contract.fields[5].htmlName)" data-strat-model="contract" data-field="contract.fields[5]" ng-click="$('#suppliername').attr('data-field', contract.fields[0]);" ></div>
    </td>
    <td>
  </tr>
</tbody>

第二个div是一个通过自定义指令（data-field-display-id）的复选框。但是点击后对第一个div data-field没有任何影响。

我做错了什么以及如何解决？

我不相信你通过混合使用jQuery和Angular来破坏任何普遍规律，但我认为这只会让事情变得更糟。我认为，面向对象的编程和Angular是最好的解决方案：

function DataField(_contract) {
  var self = this;
  this.contract = _contract;
  this.chooseField = function() {
    if (self.overrideField) {
      return self.overrideField;
    }
    else {
      return self.contract.hasOwnProperty('COMMIT_CONTRACT') ? self.contract.fields[5] : self.contract.fields[4];
    }
  };

  this.click = function(field) {
    self.overrideField = field;
  };
}

// assume this is a registered factory
function DataFieldFactory() {
  return {
    newDataField: function(contract) {
      return new DataField(contract);
    }
  }
}

function ParentController($scope, DataFieldFactory) {
  angular.forEach(contracts, function(contract) {
    contract.dataField = DataFieldFactory.newDataField(contract);
  });
}

    <td>
      <div id="suppliername" data-strat-form-control data-field-display-id="1" data-vmformreadonly="true" data-show-tool-tip="showToolTip(contract.fields[4].htmlName)" data-strat-model="contract" data-field="contract.dataField.chooseField()"></div>
