我有未捕获的引用错误：HTMLAnchorElement.onclick中未定义previous
请帮助我我已经尝试了以前为同一问题提供的所有解决方案，但没有帮助。
我已经有了jquery版本和bootstrap版本。
我将把脚本和html标记的全部代码粘贴到按钮所在的位置。
<ul class="pager wizard">
<li class="previous"><a href="javascript:;" >Previous</a></li>
<li class="next"><a href="javascript: void(0);" onclick="onPrevious(tab, navigation, index);">Next</a></li>
</ul>
<script>
$(document).ready(function() {
// You don't need to care about this function
// It is for the specific demo
function adjustIframeHeight() {
var $body = $('body'),
$iframe = $body.data('iframe.fv');
if ($iframe) {
// Adjust the height of iframe
$iframe.height($body.height());
}
}
$('#installationForm')
.formValidation({
framework: 'bootstrap',

最佳答案
一个简单的解决方案可以是在全局范围内声明它，并在jQuery范围内重用它。
<ul class="pager wizard">
<li class="previous"><a href="javascript:;" >Previous</a></li>
<li class="next"><a href="javascript: void(0);" onclick="onPrevious(tab, navigation, index);">Next</a></li>
</ul>
<script>
// Your function is declared globally.
function onPrevious(tab, navigation, index) {
return validateTab(index + 1);
}
$(document).ready(function() {
// You don't need to care about this function
// It is for the specific demo
function adjustIframeHeight() {
var $body = $('body'),
$iframe = $body.data('iframe.fv');
if ($iframe) {
// Adjust the height of iframe
$iframe.height($body.height());
}
}
$('#installationForm')
.formValidation({
framework: 'bootstrap',

valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'

编辑
这里有一个片段来证明它是有效的。
<ul class="pager wizard">
<li class="previous"><a href="javascript:;" >Previous</a></li>
<li class="next"><a href="javascript: void(0);" onclick="onPrevious('tab', 'navigation', 'index');">Next</a></li>
</ul>
<script>
// Your function is declared globally.
function onPrevious(tab, navigation, index) {
console.log(tab, navigation, index)
//return validateTab(index + 1);
}
