提问by michbeck
i try to find all id's starting with the string "matchItem_" and define a click-event for each. onclick i want wo execute a script with an url param and change the image in this id-element. unfortunatly my syntax isn't right, i also tried with .each.function but i didn't get it.
我尝试找到所有以字符串“matchItem_”开头的 ID，并为每个 ID 定义一个点击事件。onclick 我希望我们执行一个带有 url 参数的脚本并更改此 id 元素中的图像。不幸的是我的语法不正确，我也尝试过 .each.function 但我没有得到它。
please see my code:
请看我的代码：
$('[id^="matchItem_"]').each {
$(this).click(){
//...execute my script.php?urlparam=xx....;
$(this).find('img').attr('src','/admin/images/ok.png');
}
}

You don't need the each:
你不需要each：
$('[id^="matchItem_"]').click(function() {
// do something
$(this).find('img').attr('src','/admin/images/ok.png');
});

Your syntax is invalid because you forgot the functions.
您的语法无效，因为您忘记了函数。
$('[id^="matchItem_"]').each(function() {
$(this).click(function(){
//...execute my script.php?urlparam=xx....;
$(this).find('img').attr('src','/admin/images/ok.png');
});
});
Or if all you're doing is assigning the .click()handler, you can do it without the .each().
或者，如果您所做的只是分配.click()处理程序，则无需.each().
$('[id^="matchItem_"]').click(function(){
//...execute my script.php?urlparam=xx....;
$(this).find('img').attr('src','/admin/images/ok.png');
});
This is because most jQuery methods will automatically act on every element in the jQuery object.
这是因为大多数 jQuery 方法会自动作用于 jQuery 对象中的每个元素。
