jQuery .on keyup和仅模糊触发加载 [英] jQuery .on keyup and blur firing onload only

问题描述

问题: blur和keyup事件每个在加载时触发一次，并且仅在加载时触发.如何使它们正常工作?

jQuery:

Problem: The blur and keyup events each fire once onload, and only onload. How can I get them to work correctly?

jQuery:

function myFunction(text){
    alert(text);
}
$('#input1').on({
    keyup: myFunction('keyup'),
    blur: myFunction('blur'),
    focus: function(){console.log('focus!');}
});

推荐答案

您没有将函数分配给keyup和blur，而是分配了myFunction的执行结果.

You are not assigning a function to keyup and blur, you're assigning the result of the execution of myFunction.

像这样更改它:

$('#input1').on({
    keyup: function() { myFunction('keyup'); },
    blur:  function() { myFunction('blur'); },
    focus: function() { console.log('focus!'); }
});
