我有一个这样的自定义元素:
<dom-module id="customer-location">
<template>
<template is="dom-repeat" items="{{customers}}" filter="isCustomerFound" observe="cuname item.cuname">
<template is="dom-repeat" items="{{item.branches}}">
...
...
</template>
</template>
</template>
</dom-module>
该元素有一个属性cname
,其值的设置来自index.html
<customer-location cname="{{params.name}}"></customer-location>
上面的值被很好地转移到customer-location
元素中。我可以像打印它一样<p id="maxp">{{cname}}</p>
。
现在,在里面<script>...</script>
我试图cname
使用一个函数访问该属性:
<script>
(function () {
Polymer({
// define element prototype here
is: 'customer-location',
properties: {
latlngcombo: { type: String },
cname: { type: String }
},
isCustomerFound: function (item) {
var dm = this.$$("#maxp").innerHTML;
return item.cuname == dm;
},
ready: function () {
this.customers = [
{ "cuname": "msi", "name": "Microsoft India", "addr": "2, Strand Road", "addr2": "Kolkata, IN", "phone": "332.245.9910", "lat": "22.589091", "lng": "88.352359", "branches": [
{ "branch": "Hyderabad", "email": "hydho@cyfoxpapers.com", "phone": "1582012244", "address": "69/A, Twisted Road, Banjara Hills, Hyderabad: 600001", "code": "CPHYD" }
]
},
{ "cuname": "googindia", "name": "Google India Inc.", "addr": "6/B, Pragati Apartment", "addr2": "Pitampura, New Delhi, IN", "phone": "493.050.2010", "lat": "28.61598", "lng": "77.244382" },
{ "cuname": "gabonint", "name": "Gabon Internationl", "addr": "187 Kabi Kirandhan Road", "addr2": "Bhadrakali, IN", "phone": "983.193.3166", "lat": "22.665979", "lng": "88.348134" },
{ "cuname": "itg", "name": "India Tour Guides", "addr": "115/5 Palash Sarani", "addr2": "Amritsar, India", "phone": "943.390.9166", "lat": "31.604877", "lng": "74.572276" },
{ "cuname": "creatad", "name": "Creative Ad Agency", "addr": "25 BPMB Saranai", "addr2": "McLeodganj, Dharamsala. IN", "phone": "943.390.9166", "lat": "32.232596", "lng": "76.324327" }
];
}
});
})();
</script>
该函数isCustomerFound
旨在检查当前cname
值是否与item.cuname
外部dom-repeat
循环的 at 匹配。
但我从来没有从中获得价值var mm = this.$$("#maxp").innerHTML;
请告诉我我做错了什么。在另一个类似的元素this.$$("#maxp").innerHTML
中,获得了很好的价值!
