将php变量值传递给javascript函数

Question

I'm passing PHP variable value like this:

<input type="button" name="delete" value="Remove" onclick="del(<?echo $arr1[0]?>);"/>

del() is a Javascript function and Eg: $arr1[0]=234-675-90 the value of $arr1[0] is obtained from MYSQL database and its data-type in mysql is varchar.

I'm fetching value using mysql_query.

The problem I'm facing is that when value is passed to JavaScript function it takes it wrongly(eg:instead of 234-675-99 as -876).Is there any casting is to be done to pass value from PHP to JavaScript?

Any help is greatly appreciated.

Answer 1

您应该将值作为字符串传递：

<input type="button" name="delete" value="Remove" onclick="del('<?echo $arr1[0]?>');"/>

Answer 2

使用json_encode()将值转换为值JavaScript：

<input type="button" name="delete" value="Remove" onclick="del(<?=htmlspecialchars(json_encode($arr1[0]))?>);"/>
