如何在HTML中激活JavaScript函数 [英] How to make javascript function active in html
问题描述
此代码来自 http://jsfiddle.net/ejqngpn5/，但我显然将javascript和html部分错误地合并在一起，或者因为它不能像在线方式那样工作而丢失了其他内容.如何将javascript插入并在html代码中调用函数?我在脚本中使用了AJAX调用，但不知道使这两个代码片段一起工作.它应在下拉菜单中产生onClick多个复选框列表.非常感谢.
This code came from http://jsfiddle.net/ejqngpn5/ but I apparently am putting the javascript and html portions together incorrectly or am missing something else because it is not working as it did on-line. How is the javascript inserted into and the function invoked in html code? I use AJAX calls in my scripts but don't know to make these two code fragments work together. It should produce, onClick, a multiple check-box list in a drop down menu. Many thanks.
HTML:
<body>
<select size="5" name="lstStates" multiple="multiple" id="lstStates">
<option value="NJ">New Jersey</option>
<option value="NY">New York</option>
<option value="OH">Ohio</option>
<option value="TX">Texas</option>
<option value="PA">Pennsylvania</option>
</select>
</body>
JAVASCRIPT
JAVASCRIPT
$(function () {
$('#lstStates').multiselect({
buttonText: function(options, select) {
console.log(select[0].length);
if (options.length === 0) {
return 'None selected';
}
if (options.length === select[0].length) {
return 'All selected ('+select[0].length+')';
}
else if (options.length >= 4) {
return options.length + ' selected';
}
else {
var labels = [];
console.log(options);
options.each(function() {
labels.push($(this).val());
});
return labels.join(', ') + '';
}
}
});
});

您应将以下资源包括到项目中:jquery，bootstrap，bootstrap-multiselect.
