Question

我有一个文本框： -

<label>Total Amount</label>
    <input type="text" ng-model="totalAmount" disabled="disabled" ng-value="a.one+a.two+a.three+a.four" style="width:150px;height:30px"/>
The ng-value above is a sum of other four textboxes values.

还有其他六个文本框： -

<label>Total Amount</label>
        <input type="text" ng-model="b.mul1" ng-value="dividedValue(totalAmount,b.val1)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.val1" ng-value= "dividedValue(totalAmount,b.mul1)"/>
<label>Total Amount</label>
       <input type="text" ng-model="b.mul2" ng-value= "dividedValue(totalAmount,b.val2)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.val2" ng-value= "dividedValue(totalAmount,b.mul2)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.mul3" ng-value= "dividedValue(totalAmount,b.val3)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.val3" ng-value= "dividedValue(totalAmount,b.mul3)"/>

我在这里要做的是保持totalAmount并根据mul和val更改进行修复。示例： - totalAmount = mul1*val1, mul1 = totalAmount/val1, val1 = totalAmount/mul1。如果用户更改mul1，则val1更改（totalAmount / val1），反之亦然。

在我的指令代码中： -

scope.dividedValue = function(a,b){
         return a / b;
 }

但是这种方法什么都不返回。任何人都可以告诉我错误。

Answer 1

你的错误在于函数名称，它必须是“divideValue但它的divisedValue”

Answer 2

您没有传递正确的值，ng-model是b.val1，b.mul1等等，但您只是在方法中传递了val1，mul1调用

<label>Total Amount</label>
        <input type="text" ng-model="b.mul1" ng-value="dividedValue(totalAmount,b.val1)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.val1" ng-value= "dividedValue(totalAmount,b.mul1)"/>
<label>Total Amount</label>
       <input type="text" ng-model="b.mul2" ng-value= "dividedValue(totalAmount,b.val2)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.val2" ng-value= "dividedValue(totalAmount,b.mul2)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.mul3" ng-value= "dividedValue(totalAmount,b.val3)"/>
<label>Total Amount</label>
        <input type="text" ng-model="b.val3" ng-value= "dividedValue(totalAmount,b.mul3)"/>

如上所述，答案更改方法名称，因为有错字

dividedValue(a,b){
    return a/b;

}

您可以尝试以下代码。

boolean VISIBLE_PASSWORD = false;  //declare as global variable befor onCreate() 
loginPassword = (EditText)findViewById(R.id.loginPassword);
loginPassword.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if (event.getAction() == MotionEvent.ACTION_UP) {
                if (event.getRawX() >= (loginPassword.getRight() - loginPassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                    // your action here
                    //Helper.toast(LoginActivity.this, "Toggle visibility");
                    if (VISIBLE_PASSWORD) {
                        VISIBLE_PASSWORD = false;
                        loginPassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                        loginPassword.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_lock_outline_black_24dp, 0, R.drawable.ic_visibility_off_black_24dp, 0);
                    } else {
                        VISIBLE_PASSWORD = true;
                        loginPassword.setInputType(InputType.TYPE_CLASS_TEXT);
                        loginPassword.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_lock_outline_black_24dp, 0, R.drawable.ic_visibility_black_24dp, 0);
                    }
                    return false;
                }
            }
            return false;
        }
    });
