我的HTML标头中有多个脚本。需要关注的两个问题如下:
1)JS脚本(“感染数据”)产生一个带有数据的对象。数据是从Google脚本文件中检索和计算的,因此自然要花一点时间。
2)生成地图的脚本。映射根据感染对象数据的值进行颜色编码。
问题在于地图在我可以获取对象之前就已加载,因此它不会着色。

受感染的数据JS文件:

var infected_data = {};
const url = "https://script.google.com/macros/s/AKfycbzsyQNJwDvQc5SvNGEDZZOoNI3XxNar9PA9sRucZx7mgzfWpFQ/exec";
// Declare an async function
const getData = async () => {
// Use the await keyword to let JS know this variable has some latency so it should wait for it to be filled
// When the variable is fetched, use the .then() callback to carry on
const DataJSON = await fetch(url).then(response =>
response.json()
)
return await DataJSON
};
console.log(getData());
getData().then(result => {

如何jQuery(document).ready(function () {....
运行后才放慢<script type="text/javascript" src="js/jquery.vmap.sampledata.infected.js"></script>
的运行速度
答案 0 :(得分:2)
从服务器收到响应后,您可以将script元素动态地追加到文档中,如下所示:
let script = document.createElement('script');
script.src = 'myJqueryFile.js';
document.head.appendChild(script);
您只需要将这些jquery代码放入.js文件中即可。

听起来像是紧急问题...
您在哪里关闭标题?
</head>
您的onload事件在哪里同步呢?
<body onload="Function_That_KickStarts_Everything();">
答案 2 :(得分:0)
请使用正确的文档结构,并确保所有内容均以ONLOAD事件开头,以便第三方库都可以加载和同步...请遵循以下步骤:
#include <stdio.h>
_Bool wildcard_strcmp(char *line, char *pattern)
{
_Bool wildcard = 0;
char *placeholder;
do
{
if ((*pattern == *line) || (*pattern == '?'))
{
line++;
pattern++;
}
else if (*pattern == '*')
{
if (*(++pattern) == '\0')
{
return 1;
}
wildcard = 1;
}
else if (wildcard)
{
if (pattern == placeholder)
{
line++;
}
else
{
pattern = placeholder;
}
}
else
{
return 0;
}
} while (*line);
if (*pattern == '\0')
{
return 1;
}
else
{
return 0;
}
}
int main()
{
char string[200] = "foobarfoobar";
char pattern[200] = "fo?*barfoo*";
if (wildcard_strcmp(string, pattern))
{
printf("Match\n");
}
else
{
printf("No Match\n");
}
return 0;
}
