我儘量讓格顏色改變時,請單擊或側重於文本框,所以我這個js的功能,但它改變文本框顏色不是它的divJavaScript的亮點

<div class="input_text" > 
<input type="text" id="TextBox1" class="input_text" />

什麼想法?

要更改文本選擇顏色,您只需要CSS。除非沒有那麼漂亮的黑客(您需要在選擇的上方/下方的文字上繪製矩形),否則您將無法使用JavaScript來執行此操作。)

使用CSS tho您只需要執行操作(我相信):

#TextBox1::selection { 
     background: #ffb7b7; /* Safari */ 
     } 
#TextBox1::-moz-selection { 
     background: #ffb7b7; /* Firefox */ 
}

萬一一個側面說明壽你關心,這不是W3C CSS驗證。

這裏是使用JQuery一個的jsfiddle,會做什麼,我認爲你所要求的:http://jsfiddle.net/pthurlow/GG6Te/

在這裏它是在普通的香草JS:http://jsfiddle.net/FSZZU/

編輯從的jsfiddle代碼:

html

<div class="input_text"> 
    <input type="text" id="TextBox1" class="input_text" /> 
</div> 

腳本

document.getElementById('TextBox1').onfocus = function() { 
    this.parentNode.className = 'input_text focus_text'; 
}; 
document.getElementById('TextBox1').onblur = function() { 
    this.parentNode.className = 'input_text'; 
};

你可能會考慮直接包括代碼到你的答案,*與*外部的jsfiddle鏈接。這樣我們就可以保持答案的真實性,外部鏈接是對你的答案的補充。特別是當代碼相對簡短時。 – Matt 2011-05-24 14:27:59
