vla*_*dja 2 javascript innerhtml web-component svelte
我使用 Svelte 创建了简单的自定义 Web 组件。它已经编译好了，看起来应该可以很好地工作，但是有困难。我试图将一些变量传递给 prop，但总是未定义，但是如果我传递一些字符串
结果.svelte 组件
<svelte:options tag="svelte-result" />
<script>
export let result = {metadata: {}, transfers: []};
export let string = 'no string';
</script>
<div class="result__wrapper">
{string}
<div class="result__metadata">
<div>{result.metadata.offset}</div>
<div>{result.metadata.limit}</div>
<div>{result.metadata.total}</div>
</div>
</div>
当它编译时我使用它就像
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Svelte test</title>
<script defer src="/svelte/wapi-client/svelte-component.js"></script>
</head>
<body>
<div id="test"></div>
</body>
<script>
const data = {
metadata: {
limit: 20,
offset: 0,
total: 311301
},
transfers: [
{
amount: "7.95",
identifier: "9cd9901f-44a5-4436-9aef-880354bbe2e4"
}
]
};
document.getElementById('test').innerHTML = `
<svelte-result string="works" result=${data}></svelte-result>`;
</script>
</html>
data变量未传递给组件，但字符串已传递并正确显示...我做错了什么？如何将data变量传递到组件中？
You can't pass objects as attributes to custom elements. You need to stringify your object before passing it.
index.html
...
document.getElementById('test').innerHTML = `
<svelte-result string="works" result=${JSON.stringify(data)}></svelte-result>`;
...
Foo.svelte
<svelte:options tag="svelte-result" />
<script>
export let result = {metadata: {}, transfers: []};
export let string = 'no string';
$: _result = typeof result === 'string' ? JSON.parse(result) : result;
</script>
<div class="result__wrapper">
{string}
<div class="result__metadata">
<div>{_result.metadata.offset}</div>
<div>{_result.metadata.limit}</div>
<div>{_result.metadata.total}</div>
</div>
</div>
