html制作一个搜索框，代码是什么？,第1张

1、打开Hbuilder编辑器，创建一个input框和button按钮，将它们横排摆放在一起：

2、首先给input框添加“#7FCC0B”颜色的边框，设置宽度和高度即可，给button按钮设置白色的字体和“#7FCC0B”的背景颜色即可完成：

3、按crtl+s，在软件的右侧即可看到最终的效果。以上就是用html制作搜索框的演示：

分类: 电脑/网络 >>程序设计 >>其他编程语言

问题描述:

类似于按F3的功能～！

只搜索当前页中是文字～！

不要查询数据库

解析:

<>

<head>

<meta -equiv="Content-Language" content="zh-">

<meta -equiv="Content-Type" content="text/charset=gb2312">

<title>test</title>

</head>

<body class="page_speeder_724936674">

<script language="JavaScript">

var NS4 = (documentyers)Which browser?

var IE4 = (document.all)

var win = windowwindow to search.

var n = 0

function findInPage(str) {

var txt, i, found

if (str == "")

return false

Find next occurance of the given string on the page, wrap around to the

start of the page if necessary.

if (NS4) {

Look for match starting at the current point. If not found, rewind

back to the first match.

if (!win.find(str))

while(win.find(str, false, true))

n++

else

n++

If not found in either direction, give message.

if (n == 0)

alert("本页没有查到.")

}

if (IE4) {

txt = win.document.body.createTextRange()

Find the nth match from the top of the page.

for (i = 0i <= n &&(found = txt.findText(str)) != falsei++) {

txt.moveStart("character", 1)

txt.moveEnd("textedit")

}

If found, mark it and scroll it into view.

if (found) {

txt.moveStart("character", -1)

txt.findText(str)

txt.select()

txt.scrollIntoView()

n++

}

Otherwise, start over at the top of the page and find first match.

else {

if (n >0) {

n = 0

findInPage(str)

}

Not found anywhere, give message.

else

alert("本页没有查到此题目，请尝试用下百度的搜索引擎在网上查下.")

第一步

在网页中引入Javascript文件：

第二步

在Javascript程序中调用BaiduSuggestion.bind()方法将“百度搜索框提示”功能和页面上的元素 进行绑定。

BaiduSuggestion.bind()的具体形式为：

BaiduSuggestion.bind(inputObj|inputId,[params],[confirmCallback])inputObj|inputId:

为需要绑定搜索框提示功能的input对象或input对象的id。

params:

绑定搜索框提示功能时用到的参数，必须以Json形式给出,例如：

{

"XOffset":0, //提示框位置横向偏移量,单位px

"YOffset":0, //提示框位置纵向偏移量,单位px

"width":350, //提示框宽度，单位px

"fontColor":"#03c", //提示框文字颜色

"fontColorHI":"#FFF", //提示框高亮选择时文字颜色

"fontSize":"12px", //文字大小

"fontFamily":"宋体", //文字字体

"borderColor":"#03c", //提示框的边框颜色

"bgcolorHI":"#fd0", //提示框高亮选择的颜色

"sugSubmit":false //选中提示框中词条时是否提交表单

}

confirmCallback(txt):

当用户选择提示中具体选项时的回调函数，txt为用户选择的内容。

提示：

如果网页中有多个输入框需要添加“百度搜索框提示”功能，请为每个输入框都加上baiduSug属性。

Javascript代码请添加到网页中</body>标签的后面。

如使用utf-8编码，请务必在script标签中设置charset=gbk属性，否则搜索提示词会出现乱码。
