使用window.open将变量传递给新的HTML

Im opening html file from js function:

我从js函数打开html文件:

function initCategoryPage(url){
    var catUrl=url;
    window.open("category.html");
}

I putted this script in "category.html" but it doesnt get the var catUrl:

我把这个脚本放在“category.html”中,但它没有得到var catUrl:

<script>
    myUrl = window.opener.catUrl;
    alert(myUrl)
    id=1;
    firstTime=true;
    ArticlesBlock(); 
</script>

how can I pass it to category.html?

我怎样才能将它传递给category.html?

1 个解决方案

The reason it can not read it is because the variable is not global. The scope is limited to that method.

它无法读取它的原因是因为变量不是全局变量。范围仅限于该方法。

function initCategoryPage(url){
    window.catUrl=url;  /*make it global*/
    window.open("category.html");
}

A better solution would be to pass it as a querystring or use postMessage to get the value.

更好的解决方案是将其作为查询字符串传递或使用postMessage获取值。
