我正在尝试使用这个Flickr jsonp Vue示例(https://codepen.io/tomascherry/pen/GrgbzQ)并将其变成一个组件。但是,我无法弄清楚如何将jsonFlickrFeed()
映射到this.jsonFlickrFeed()
(一旦该函数放置在组件的methods: {}
内部)。
代码如下:
<template>
<!-- HTML HERE -->
</template>
<script>
let callApiTimeout = null
export default {
name: 'Flickr',
filters: {
splitTags: function(value) {
// showing only first 5 tags
return value.split(' ').slice(0, 5)
}
},
directives: {
/* VueJs utilites */
img: {
inserted: function(el, binding) {
this.lazyload(el, binding)
},
update: function(el, binding) {
this.lazyload(el, binding)
}
}
},
data() {
return {
images: [],
query: ''
}
},
watch: {
query: function(value) {
clearTimeout(callApiTimeout)
callApiTimeout = setTimeout(
function() {
const reqURL =
'https://api.flickr.com/services/feeds/photos_public.gne'
const options = {
params: {
format: 'json',
tags: this.query,
jsoncallback: 'this.jsonFlickrFeed'
}
}
this.$http.jsonp(reqURL, options)
}.bind(this),
250
)
}
},
methods: {
/* JSONP callback function */
jsonFlickrFeed(response) {
this.$data.images = response.items
},
/* General utility functions */
lazyload(el, binding) {
const img = new Image()
img.src = binding.value
img.onload = function() {
el.src = binding.value
}
}
}
}
</script>
<style lang="less">
/* STYLE HERE */
</style>
我尝试添加jsoncallback: 'this.jsonFlickrFeed'
参数,但这无济于事。
答案 0 :(得分:0)
为简化起见,只需传递参数nojsoncallback=1
,它将直接返回JSON对象。
