我该怎么做才能实现这一目标.我希望如果我点击imgThumb1图像,该图像的src被复制mainIMG,但是当我点击它时图像不会改变...我该怎么办？
$(document).ready(function(){
$('.propertyResultImageThumb img[alt="imgThumb1"]').click(function(){
var trial = $('img[alt="imgThumb1"]').attr('src');
$("#mainIMG").attr("src", trial);
});
});
<img alt="mainIMG" src="" id="mainIMG"/>
<img alt="imgThumb1" src="http://..../uploads/2012/09/Villa-Located-In-Almansa.jpg" />
我想制作一个像这样的数组
$array = array("'firstName1', 'lastName1'", "'firstName2', 'lastName2'", ......);
我总是得到这样的错误:
解析错误:第11行的C:\ wamp\www\Tests\index.php中的语法错误,意外'while'(T_WHILE),期待')'

<?php
if(isset($_POST['reg'])){
$x=1;
$a = array(
while($x<=10):
"'firstName$x', 'lastName$x'"; //I DONT KNOW WHAT TO DO IN THIS LINE//
$x++;
endwhile;
);
print_r($a);
}
?>

<td><input type='text' name='lastName$i' /></td>
</tr>";
}
$i-=1;
echo "<input type='hidden' name='hide' value='$i' …这是我的代码
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<script src="js/jquery-1.7.2.min.js"></script>
<style>
div{
border:2px solid black;
width:200px;
min-height:300px;
}
</style>
</head>
<body>
<div>
<p id="demo">This will change</p>
<input type="button" value="OK" onclick="myFunction()"/>
</div>
<script>
$(document).ready(function()

$("input").click(function()
{
if($("div").height("300px") === true){
document.getElementById("demo").innerHTML="HELLO WORLD!";
}
});
});
</script>
</body>
</html>
我想这样做,如果div高度等于300px,"这将改变"段落将点击一个按钮改为Hello World.对不起,这是我第一次使用javascript
这是我的代码:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Date Picker</title>
</head>
<body>
<p>Click the button to loop through a block of code five times.</p>
<button onclick="myFunction()">Try it</button>
<select id="demo">
</select>
<p id="demo"></p>
<script>
function myFunction()
{
var i;
for (i=1;i<=5;i++){
document.getElementById("demo").innerHTML="<option value="+i+">"+i+"</option>";
}
}
</script>
</body>
</html>
我想要的是当我按下按钮下拉框时会生成如下选项:
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
但我只得到这个代码
<option value="5">5</option>
它只显示选项上的5.请帮忙..谢谢
