我有一些构建名为myList[]
的数组的jQuery代码。这个数组出现在控制台中,如下所示:["2 items", "3items", "so on"]
,所以这一部分进展顺利。
<script type="text/javascript">
var myList = [];
function buld myList(){
...
}
我需要将myList[]
传递给application/ld+json
<script type="application/ld+json">
{
"@context": "http://schema.org/",
"@type": "Recipe",
"recipeIngredients": myList, //this one doesn't work
}
..
如何将值从javascript传递到application/ld+json
?提前谢谢!
答案 0 :(得分:8)
请试试这个:
<script id="myJSONID" type="application/ld+json"></script>
然后:
var myList = [];
function buildMyList() {
return ["2 items", "3items", "so on"];
}
$("#myJSONID").text(function() {
return JSON.stringify({
"@context": "http://schema.org/",
"@type": "Recipe",
"recipeIngredient": buildMyList()
});
});
或者:
<script type="text/javascript">
var myList = [];
function buildMyList() {
return ["2 items", "3items", "so on"];
}
var el = document.createElement('script');
el.type = 'application/ld+json';
el.text = JSON.stringify({
"@context": "http://schema.org/",
"@type": "Recipe",
"recipeIngredient": buildMyList()
});
document.querySelector('body').appendChild(el);
</script>

注意:请确保将recipeIngredients
更改为recipeIngredient
,这是单数。 (谢谢@AlexKudryashev)。
