網頁上默認的文本框總是灰色風格,看的都有點不耐煩了,用CSS和JS改變其樣式是你們都喜歡用的方法,今天寫了一個點擊邊框變色的文本框,鼠標點擊文本框將要輸入的時候,文本框自動變色高亮顯示,很是有視覺效果,讓文本框變漂亮了許多。HTML代碼以下:javascript

< script type = "text/javascript" > |

// focusClass : 獲取焦點時的樣式 |
10 |
// normalClass : 正常狀態下的樣式 |
11 |
function focusInput(focusClass, normalClass) { |
12 |
var elements = document.getElementsByTagName("input"); |
13 |
for (var i=0; i < elements.length ; i++) { |
14 |
if (elements[i].type != "button" && elements[i].type != "submit" && elements[i].type != "reset") { |
15 |
elements[i] .onfocus = function () { this.className = focusClass ; }; |
16 |
elements[i] .onblur = function () { this.className = normalClass ||''; }; |
17 |
} |
18 |
} |
19 |
} |
20 |
</script> |
21 |
< script type = "text/javascript" > |
22 |
window.onload = function () { |
23 |
focusInput('focusInput', 'normalInput'); |
24 |
} |
25 |
</ script > |
26 |
請輸入姓名:< input type = "text" class = "normalInput" /> |
27 |
< style type = "text/css" > |
28 |
.normalInput {border:1px solid #ccc;} |
29 |
.focusInput {border:1px solid #FFD42C;} |
30 |
</ style > |
31 |
</ body > |

</ html > |
在火狐下也有效,只不過火狐和chrome下,這兩款瀏覽器默認會自動會輸入框添加點擊效果,因此有時候看不清,IE下表現突出。css
