需要一些jquery / js / jsp功能的帮助..
我有一个可折叠的表脚本:
(function($){
$.fn.extend({
setupCollapstable: function(options) {
var defaults = {
displayStyle: "Image",
autoCheckbox: true,
toggleMinus: "/resource/images/collapse_close.gif",
togglePlus: "/resource/images/collapse_open.gif"
};
var options = $.extend(defaults, options);
var toggleMinus = options.toggleMinus
var togglePlus = options.togglePlus
return this.each(function() {
//Creating a reference to the object
var obj = $(this);
//Break out the individual tbody elements
var rowGroups = $('tbody', obj);
//Loop through every tbody to setup collapsable and click events
$.each( rowGroups, function( intIndex, objValue ){
parentRow = $('th:first-child', objValue);
childCount = parentRow.parent().siblings().length;
if (childCount != 0) {
//console.log ("ParentRow: " + parentRow + " - ChildCount is: " + childCount);
parentRow.prepend('<img src="' + togglePlus + '" alt="collapse this section" />');
parentRow.parent().siblings().fadeOut('fast');
$('img', parentRow).addClass('clickable').click(function(e) {
e.preventDefault();
var toggleSrc = $(this).attr('src');
if ( toggleSrc == toggleMinus ) {
$(this).attr('src', togglePlus).parents('tr').siblings().fadeOut('fast');
} else{
$(this).attr('src', toggleMinus).parents('tr').siblings().fadeIn('fast');
};
});
var parentCheckbox = $(':checkbox', parentRow.siblings())
var childCheckboxes = $(':checkbox', parentRow.parent().siblings());
parentCheckbox.click(function(e){
var checked_status = parentCheckbox.attr('checked')?1:0;
childCheckboxes.each(function(){
this.checked = checked_status;
});
});
} else {
parentRow.addClass("indented");
}
});
//console.dir (objValue);
});
}
});
})(jQuery);
从我的JSP中我称之为......
<script type="text/javascript" src="/resource/js/jquery.collapstable.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('table.collapstable').setupCollapstable();
});
</script>
用法:
<table class="collapstable NoTableBorder">
当我单击图像图标时,表格会正确折叠和展开,但是如果选中某个复选框(在JSP上),我希望它最初展开。
所以我会为该复选框输入一个onclick =“showOrHide()”函数,它会折叠或展开表格。
我附加了一个图像用于可视化表示,collpase表是“+/-”图标(在粗体VISA标题旁边),而复选框决定是否应该展开以显示“活动” “复选框..
对此的任何帮助都会很棒......

您可以在崩溃/展开函数调用之前添加条件
<script type="text/javascript">
$(document).ready(function(){
if (checkboxname.checked){
// Set flags to show the table expanded
}else{
// Set flags to show the table collapsed
}
$('table.collapstable').setupCollapstable();
});
</script>
