單獨(dú)輸出文字

$jieshou.append("<p>"+$content+"</p>");

是可以正常發(fā)送的，但是加了圖片后也就是加了$img后就顯示為object Object+"發(fā)送的內(nèi)容",真的搞不懂了，單獨(dú)輸入$img 也是可以的 請(qǐng)大佬幫我看一下究竟是什么問題

$img是個(gè)JQery對(duì)象.

當(dāng)它和字符串進(jìn)行+操作時(shí),相當(dāng)于調(diào)用了toString().

而$content也是JQuery對(duì)象,它和字符串進(jìn)行+操作后也變成了String.但是$content本身是String對(duì)象.所以這里看不出來變化.

$jieshou.append($img?+?"<P>"?+?$content?+?"</p>");

改寫成

$jieshou.append($img,?"<P>"?+?$content?+?"</p>");

這樣就沒問題了.
