我正在从<div>
标签中搜索文本。问题是当我搜索时,我的所有<div>
数据都集中在一行。
这是我的小提琴。 http://jsfiddle.net/Fc4Sg/
在小提琴中,输入break然后按搜索。为什么<div>
内容不保持其格式?
这是我的代码:
var searchIndex = -1;
var searchTermOld ='';
$(document).ready(function(){
$('.searchbox').on('change',function(){
if($(this).val()===''){
var selector = "#realTimeContents";
$(selector+' span.match').each(function(){
$(this).replaceWith($(this).html());
});
}
searchIndex = -1;
$('.searchNext').attr("disabled", "disabled");
$('.searchPrev').attr("disabled", "disabled");
searchTermOld = $(this).val();
});
$('.searchbox').on('keyup',function(){
var selector= "#realTimeContents";
if($(this).val()===''){
$(selector+' span.match').each(function(){
$(this).replaceWith($(this).html());
});
}
if($(this).val() !== searchTermOld){
$(selector+' span.match').each(function(){
$(this).replaceWith($(this).html());
});
searchIndex = -1;
$('.searchNext').attr("disabled", "disabled");
$('.searchPrev').attr("disabled", "disabled");
}
});
$('.search').on('click',function(){
if(searchIndex == -1){
var searchTerm = $('.searchbox').val();
if(searchTerm==''){
PG_alert("Please Insert Text.")
return;
}
searchAndHighlight(searchTerm);
}
else
searchNext();
if($('.match').length >1){
$('.searchNext').removeAttr("disabled");
$('.searchPrev').removeAttr("disabled");
}
});
$('.searchNext').on('click',searchNext);
$('.searchPrev').on('click',searchPrev);
});
function searchAndHighlight(searchTerm) {
if (searchTerm) {
var searchTermRegEx, matches;
var selector= "#realTimeContents";
$(selector+' span.match').each(function(){
$(this).replaceWith($(this).html());
});
try {
searchTermRegEx = new RegExp('('+searchTerm+')', "ig");
} catch (e) {
return false;
}
$('.highlighted').removeClass('highlighted');
matches = $(selector).text().match(searchTermRegEx);
if (matches !==null && matches.length > 0) {
var txt = $(selector).text().replace(searchTermRegEx, '<span class="match">$1</span>');
$(selector).html(txt);
searchIndex++;
$('.match:first').addClass('highlighted');
if($('.match').eq(searchIndex).offset().top > $(window).height()-10){
$(document).scrollTop($('.match').eq(searchIndex).offset().top);
}
return true;
}else{
PG_alert('Search not found.');
}
return false;
}
return false;
}
function searchNext(){
searchIndex++;
if (searchIndex >= $('.match').length)
searchIndex = 0;
$('.highlighted').removeClass('highlighted');
$('.match').eq(searchIndex).addClass('highlighted');
if($('.match').eq(searchIndex).offset().top > $(window).height()-10){
$(document).scrollTop($('.match').eq(searchIndex).offset().top);
}
}
function searchPrev(){
searchIndex--;
if (searchIndex < 0)
searchIndex = $('.match').length - 1;
$('.highlighted').removeClass('highlighted');
$('.match').eq(searchIndex).addClass('highlighted');
if($('.match').eq(searchIndex).offset().top > $(window).height()-10){
$(document).scrollTop($('.match').eq(searchIndex).offset().top);
}
}
