本文實(shí)例講述了js實(shí)現(xiàn)仿Discuz文本框彈出層效果。分享給大家供大家參考。具體如下：
這是一個(gè)在經(jīng)典論壇曾經(jīng)熱討論的問題，記得在QQ郵箱里也有類似功能，Discuz7.0論壇里同樣也有，當(dāng)你的鼠標(biāo)單擊文本框的時(shí)候，會(huì)彈出一個(gè)包含文字、圖片、表單無素的DIV層，里面的元素都可以進(jìn)行操作，很方便，選中的值會(huì)自動(dòng)添加到文本框內(nèi)。本代碼經(jīng)過了多次修正，沒有進(jìn)行過多美化，你美工好的話可以自己美化。
運(yùn)行效果截圖如下：
具體代碼如下：
