Pass PHP Variable into Java Script window.location
提问by pixelJockey
I am trying to pass a php variable into a java script window.location that returns a user to the current list view after deleting an item from the database. I can't seem to get the syntax correct.
我试图将一个 php 变量传递到一个 java 脚本 window.location 中，该脚本在从数据库中删除一个项目后将用户返回到当前列表视图。我似乎无法获得正确的语法。
Code:
代码：
function confirmation(a) {
var currString = "<? echo $currString ?>";
var answer = confirm("Are you sure you want to delete this item?")
if (answer){
alert("The item has been deleted")
window.location = "list.php?s='. $currString .'&=delete=true&id=" + a;
}
else{
alert("The item has not been deleted")
}

The syntax issue was solved by other answers, but you need to take care of an additional issue: URI encodingyour variable when you use it in the URL:
语法问题已由其他答案解决，但您需要注意另一个问题：在 URL 中使用变量时对变量进行URI 编码：
window.location = "list.php?s="
+ encodeURIComponent(currString)
+ "&=delete=true&id=" + a;
or else you will run into problems of your variable contains characters like &.
否则你会遇到你的变量包含像&.

you are pasing php variable to JS variable var currString = "";
您正在将 php 变量传递给 JS 变量 var currString = "";
and in window.locationyou are passing again php variable which is wrong,
并且在window.location您再次传递错误的 php 变量中，
so do it like this
所以这样做
window.location = "list.php?s=" + currString + "&=delete=true&id=" + a;

echo "<script>alert('System info has been Save')</script>";
echo "<script>window.location='customer_detail.php?
customer_id=".$customer_id."'</script>";
