我试图添加一个简单的等待框'在javascript函数上,像这样:
function caricaElenco(indice) {
(...)
$("[id*=Wait1_WaitBox]").show(); // Visualizzo 'rotella' caricamento
(...)
$("[id*=Wait1_WaitBox]").hide();
}
它在Firefox上工作得很好,但在Internet Explorer 11上却没有显示出来。 HTML是:
<div id="ctl00_Wait1_WaitBox" class="updateProgress">
Attendere...<br />
<img src="../Images/wait.gif" align="middle" />
</div>
最奇怪的是我试试这个,进行简单的检查:
function caricaElenco(indice) {
(...)
alert($("[id*=Wait1_WaitBox]").css('display'))
$("[id*=Wait1_WaitBox]").show(); // Visualizzo 'rotella' caricamento
alert($("[id*=Wait1_WaitBox]").css('display'))
(...)
$("[id*=Wait1_WaitBox]").hide();
}
而且它正在工作,我的意思是它会显示警告,并且没有&#39;没有&#39;阻止&#39;阻止&#39; ...它也显示了这个盒子!但不是没有警报......为什么?
更新
尝试使用[id*="Wait1_WaitBox"]
,但它是一样的。 jQuery版本是1.8.2。
用
它只能使用警报
我的意思是,如果我这样做:
function caricaElenco(indice) {
(...)
alert('whatever');
$("[id*=Wait1_WaitBox]").show(); // Visualizzo 'rotella' caricamento
alert('whatever');
(...)
$("[id*=Wait1_WaitBox]").hide();
}
它显示了该框,但如果我这样做:
function caricaElenco(indice) {
(...)
$("[id*=Wait1_WaitBox]").show(); // Visualizzo 'rotella' caricamento
(...)
$("[id*=Wait1_WaitBox]").hide();
}
它没有工作(我的意思是没有显示等待框&#39;,而是执行函数必须执行的所有其他操作(...)正确加载网格视图在Internet Explorer 11上的AJAX调用,在Firefox中都有效。没有JavaScript错误。
更新2: 几乎整个javascript函数:
// Fill part of gridView
function loadList(index) {
index = parseInt(index);
buffer = 100; // Number of rows to load
$("[id*=divGrid]").unbind('scroll');
$('[id*="Wait1_WaitBox"]').show(); // Show loading 'wheel'
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "PageName.aspx/webMethodName",
data: '{id:' + $("[id*=hdnID]").val() + ', index:' + index + '}',
dataType: "json",
async: false,
success: function (response) {
if (index == 0) {
(...)
$("[id*=grid] tr:last-child").remove();
var row = "<tr class='" + response.d[index].State + "'>";
row += "<td class="Column1"></td>";
(...)
row += "<td class="DateColumn"></td>";
(...)
row += "<td class='columnN'></td></tr>";
$("[id*=grid]").append(row);
}
row = $("[id*=grid] tr:last-child").clone(true);
$("[id*=grid] tr:last-child").remove();
if (index <= response.d.length) {
if (index + buffer > response.d.length)
var stop = response.d.length;
else
var stop = index + buffer;
(...)
for (var i = index; i < stop; i++) {
var j = 0;
(...)
$("td", row).eq(j).html("<span id='lblCodeNumber" + i + "' >" + response.d[i].CodeNumber + "</span>"); j++;
(...)
var effectDate = new Date(parseInt(response.d[i].effectDate.substr(6)));
$("td", row).eq(j).html(effectDate.getDate() + '/' + (effectDate.getMonth() + 1) + '/' + effectDate.getFullYear()); j++;
}
(...)
var toBeCounted = "";
var checked = "";
if (response.d[i].ToBeCounted != null)
toBeCounted = response.d[i].ToBeCounted .toString();
else
toBeCounted = "true";
if (toBeCounted == "true")
checked = "checked = 'checked'";
else
checked = "";
var rdToBeCounted = "<span><input type='radio' class='radio' " + checked + " name='ToBeCounted" + i + "' value='s' id='sToBeCounted" + i + "' />";
rdToBeCounted += "<label for='s" + i + "'>YES</label>";
if (toBeCounted == "false")
checked = "checked = 'checked'";
else
checked = "";
toBeCounted += "<input type='radio' class='radio' " + checked + " name='ToBeCounted" + i + "' value='n' id='nToBeCounted" + i + "' />";
rdToBeCounted += "<label for='n" + i + "'>NO</label></span>";
$("td", row).eq(j).html(rdToBeCounted);
$("[id*=grid]").append(riga);
(...)
riga = $("[id*=grid] tr:last-child").clone(true);
}
if (stop < response.d.length) {
$("[id*=divGrid]").scroll(function (e) {
if (element_in_scroll(".congruenti tbody tr:last")) {
loadList($(".congruenti tbody tr:last td:last").html());
};
});
}
$('[id*="Wait1_WaitBox"]').hide();
}
},
error: function (result) {
alert("Error! " + result.status + " - " + result.statusText);
}
});
}
答案 0 :(得分:2)
最后你似乎又隐藏了它$("[id*=Wait1_WaitBox]").hide();
。
您需要显示这两行之间的内容。
它与alert
一起使用,因为脚本的执行被冻结,直到您关闭警报(并且最后一行尚未执行)。
