我和 Jquery 在一起。
我将 html 附加到这样的 div 中:
$('div#byletter').append(createLettersHtml());
createLettersHtml 函数创建一个包含在“div.ln-letters”中的字母(链接)列表。然后我想像这样调用“onclick”事件:
$('.ln-letters a').click(function(){
alert(123);
});
但什么也没发生!如果我在任何未附加的 html 元素上调用 onclick ,它可以工作,但它不适用于附加的内容。我做错了什么?
更新:
这是完整的代码:
$(document).ready(function(){
$.fn.listnav = function(options) {
var opts = $.extend({}, $.fn.listnav.defaults, options);
var letters = ['_', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '-'];
var firstClick = false;
opts.prefixes = $.map(opts.prefixes, function(n) { return n.toLowerCase(); });
$('div#byletter').append(createLettersHtml());
function createLettersHtml() {
var html = [];
for (var i = 1; i < 27; i++) {
if (html.length == 0) html.push('<a class="all" href="#">ALL</a><a class="_" href="#">0-9</a>');
html.push('<a class="' + letters[i] + '" href="#">' + ((letters[i] == '-') ? '...' : letters[i].toUpperCase()) + '</a>');
}
return '<div class="ln-letters">' + html.join('') + '</div>' + ((opts.showCounts) ? '<div class="ln-letter-count" style="display:none; position:absolute; top:0; left:0; width:20px;">0</div>' : ''); // the styling for ln-letter-count is to give us a starting point for the element, which will be repositioned when made visible (ie, should not need to be styled by the user)
}
};
$.fn.listnav.defaults = {
initLetter: '',
includeAll: true,
incudeOther: false,
includeNums: true,
flagDisabled: true,
noMatchText: 'No matching entries',
showCounts: true,
cookieName: null,
onClick: null,
prefixes: []
};
$('.ln-letters a').click(function(){
alert(123);
});
});
