[英]Polymer 1.0 Adding variables in a polymer function
I am not sure if this is a bug or i am doing something wrong. 我不确定这是否是错误或我做错了什么。
I have 6 properties 我有6个住宿
(function () {
Polymer({
is: 'claim-type',
properties: {
foo: {
type: Number,
value: false,
observer: 'add'
},
bar: {
type: Number,
value: false,
observer: 'add'
},
....
and so on.... 等等....
Each one is linked to a 每个链接到一个
When one changes it triggers the observer 'add' 更改时会触发观察者“添加”
add: function () {
this.ray = this.bar + this.foo + this.etc;
}
say foo = 1 and bar = 2 and etc = 3 说foo = 1和bar = 2等等= 3
the result will equal 123 instead of 6? 结果等于123而不是6?
What am i doing wrong? 我究竟做错了什么?
EDIT : changed code from type Boolean to Number 编辑 :将代码从布尔类型更改为数字
Polymer seems to be treating the Numbers as strings. Polymer似乎将数字视为字符串。 This is probably do to the fact it is using paper-input
这可能是因为它使用纸张输入
need to add the + sign in front of the variable to convert it into a number. 需要在变量前面添加+号,以将其转换为数字。
add: function () {
this.ray = +this.bar + +this.foo + +this.etc;
}
