jQuery在Smarty代码上引发未捕获的错误

Question

I have the following error message

Uncaught Error: Syntax error, unrecognized expression: [value={if isset($smarty.post.id_state)}{$smarty.post.id_state|intval}{/if}]

Which originating from this code:

$('.id_state option[value={if isset($smarty.post.id_state) {$smarty.post.id_state|intval}{/if}]').prop('selected', true);

I am not sure why it throws such error, since the code following it (literallly the next line) works like a charm

The following code works normally

$('.id_state_invoice option[value={if isset($smarty.post.id_state_invoice)}{$smarty.post.id_state_invoice|intval}{/if}]').prop('selected', true);

Answer 1

isset（）之后，您缺少结束符}。

Answer 2

your code:

{if isset($smarty.post.id_state) {$smarty.post.id_state|intval}{/if}

needs to be:

{if isset($smarty.post.id_state)}{$smarty.post.id_state|intval}{/if}
