我被迫使用 jQuery Mobile,尽管它是一个构建良好的系统,但我还是有些犹豫。因此,我有一个在任何复选框更改时提交的表单。客户希望这样,当他们单击一个页面时,页面会等待一段时间提交,这样,如果选择另一个页面,则不会触发前一个请求,而会触发新请求。它本质上是为了减少即时性并允许更有效的过滤/请求。我的代码是这样的:
$( function() {
var sForm = "form[name='Waves']",
sCboxes = "input[type='checkbox']",
sWaves = "";
var $Cboxes = $(sForm + " " + sCboxes),
sChecked = sCboxes + ":checked";
$Cboxes.change( function(event) {
var $this = $(this);
if ( $this.attr("id") != "ClearAll" ) {
console.debug($(this));
console.debug('Changing page.');
sWaves = "";
// Form the string for the selected waves with standard check-if-it's-the-last
// element logic for comma generation.
$.each( $(sChecked) , function(i, v) {
var $this = $(this);
var iIndex = v.value;
sWaves += iIndex + ( ( i == $(sChecked).length - 1 ) ? "" : "," );
} );
console.debug("Waves to select: " + sWaves);
$.mobile.changePage("default.asp", {
data: { Wave: sWaves }, // Submit the previously formed string
type: "post"
} );
//$(sForm).submit();
} else {
$(sChecked).add( $(this) ).attr("checked", false).checkboxradio("refresh");
$.mobile.changePage("default.asp", {
data: { Wave: "" },
type: "post"
} );
}
} );
$("#ClearAll").click( function(event) {
event.preventDefault();
} );
$(".slideout").click( function(){
$(this).parents(".ui-collapsible").find(".ui-icon-minus").click();
} );
} );
表单的 HTML:
<form ACTION="<%=ASP_SELF()%>" ID="Waves" METHOD="post" NAME="Waves">
<% ' Put the scripts we need here so that it loads with the page. %>
<script SRC="/base/scripts/scripts.js"></script>
<fieldset DATA-ROLE="controlgroup" DATA-TYPE="horizontal" STYLE="margin-left:5px; margin-bottom:0px; ">
<input TYPE="checkbox" NAME="#" ID="#" VALUE="Select Waves" CLASS="custom" />
<label CLASS="no-hover" FOR="#"> Waves: </label>
<input TYPE="checkbox" NAME="Wave1" ID="Wave1" VALUE="1" CLASS="custom" STYLE="width:70px !important; " <% If Instr(request("Wave"),"1") OR WaveOne = "YES" Then response.write " checked=""checked""" End If %> />
<label FOR="Wave1"> 1 </label>
<input TYPE="checkbox" NAME="Wave2" ID="Wave2" VALUE="2" CLASS="custom" STYLE="width:70px !important; " <% If Instr(request("Wave"),"2") OR WaveTwo = "YES" Then response.write " checked=""checked""" End If %> />
<label FOR="Wave2"> 2 </label>
<input TYPE="checkbox" NAME="Wave3" ID="Wave3" VALUE="3" CLASS="custom" STYLE="width:70px !important; "<% If Instr(request("Wave"),"3") OR WaveThree = "YES" Then response.write " checked=""checked""" End If %> />
<label FOR="Wave3"> 3 </label>
<input TYPE="checkbox" NAME="Wave4" ID="Wave4" VALUE="4" CLASS="custom" STYLE="width:70px !important; "<% If Instr(request("Wave"),"4") OR WaveFour = "YES" Then response.write " checked=""checked""" End If %> />
<label FOR="Wave4"> 4 </label>
<input TYPE="checkbox" NAME="ClearAll" ID="ClearAll" VALUE="Clear" CLASS="custom" $('input[data-type="search"]').TRIGGER("CHANGE").VAL(""); />
<label FOR="ClearAll"> Clear </label>
</fieldset>
</form>
我需要延迟 $.mobile.changePage
调用足够长的时间以允许其他相关的复选框(在同一字段集中)也被切换。我感谢任何输入!这是一件非常重要的事情。
最佳答案
var timer;
var waitTime = 2000;
$Cboxes.change( function(event) {
if(timer)clearTimeout(timer);
timer = setTimeout(function(){
//your logic
},waitTime);
});
当触发更改事件时,要执行的操作计划在 2000 毫秒后执行, 如果用户在此之前改变主意,只需清除间隔并创建一个新间隔即可
