JQuery click() 不工作
JQuery click() not working
这是最奇怪的事情:
$(document).ready(function() {
$( ".selector" ).first().css( "background-color", "red" ); // This works
$( ".selector" ).first().click(); // This doesn't
$( ".selector" ).click(function(e) {
alert("plop");
});
});
当然,当我单击 .selector
时,我确实看到了警报...是什么原因?
想想你做事的顺序:
//click the first .selector:
$( ".selector" ).first().click();
//from now on, when .selector is clicked, fire an alert
$( ".selector" ).click(function(e) {
alert("plop");
});
如果你这样做:
//from now on, when .selector is clicked, fire an alert
$( ".selector" ).click(function(e) {
alert("plop");
});
//click the first .selector:
$( ".selector" ).first().click();
它应该有效
在此之后您可能会捂脸,但您在添加点击处理程序之前调用了点击事件。您的代码是这样写的:
Click on the first .selector
If any .selectors get clicked on from now on, do this function
如果将 click
处理程序移动到 .click()
调用上方,它将正常工作。
