i have a html
<a class="list_size" onclick="generate_size(<?php echo htmlspecialchars(json_encode($ukuran));?>);return false;" title="<?php echo $warna[$w]['warna']; ?>"><?php echo $warna[$w]['warna']; ?></a>
and this is the json of php variable of $ukuran
echo json_encode($ukuran);
output : [{"uk":"26"},{"uk":"27"},{"uk":"28"},{"uk":"29"},{"uk":"30"},{"uk":"31"},{"uk":"32"},{"uk":"33"},{"uk":"34"},{"uk":"35"}]
and this is the function of javascript
function generate_size(ukuran) {
alert(ukuran.length + ukuran.uk[0])
}
when i using alert(ukuran.length)
that will shown alert with 10, and that is correct.. but when i using alert(ukuran.length + ukuran.uk[0])

if i see the json_encode above, if i alert(ukuran.uk[0])
that should be shown 26

我需要json_encode的帮助 p>
我有一个html p >
&lt; a class =“list_size”onclick =“generate_size(&lt;?php echo htmlspecialchars(json_encode($ ukuran));?&gt;); return false;” title =“&lt;?php echo $ warna [$ w] ['warna'];?&gt;”&gt;&lt;?php echo $ warna [$ w] ['warna']; ?&gt;&lt; / a&gt;
code> pre>
这是$ ukuran的php变量的json p>
echo json_encode($ ukuran);
output:[{“uk”:“26”},{“uk”:“27”},{“uk”:“28”},{“uk”:“29”} ,{ “英国”: “30”},{ “英国”: “31”},{ “英国”: “32”},{ “英国”: “33”},{ “英国”: “34”} ,{“uk”:“35”}]
code> pre>
这是javascript p>
函数的功能 generate_size(ukuran){
alert(ukuran.length + ukuran.uk [0])
}
code> pre>
当我使用 alert时( ukuran.length) code>将显示10的警报,这是正确的..但当我使用 alert(ukuran.length + ukuran.uk [0]) code>我失败时调用此 函数.. p>
如果我看到上面的json_encode,如果i alert(ukuran.uk [0]) code>应该显示26 p>
如何解决这个问题..我试图在谷歌找到它但没有找到工作解决方案,
有人帮我? 谢谢 p>

It appears that ukuran[0] is {"uk":"26"} and not simply 26. Are you sure you aren't looking for ukuran[0].uk?
Try casting your string to an int
alert(ukuran.length + parseInt(ukuran.uk[0]));
