当单击后退按钮时,我想用已加载的变量data1填充结果div。使用此代码,单击后退按钮时,结果div将设置为""。如何访问较新版本的data1?
Javascript:
function finddata(def,id){
$("#doctitle").html($("#exp").val() + " - Writer's Dictionary");
$("#results").html('<span class="glyphicon glyphicon-cog glyphicon-spin" title="loading..."></span>').fadeIn();
if (def == 1) {
var word = id.innerHTML;
$.get( "processor.php?query=" + word + "&def=" + def, function(data2) {
$("#results").html(data2);
$("#back").click(function(){
$("#results").html(data1);
});
});
} else {
$.get( "processor.php?query=" + $("#exp").val(), function(data1) {
$("#results").html(data1);
});
}
}
HTML:
<div class="container">
<div class="col-md-6 col-md-offset-3" id="results">
<div id="back">Back</div>
</div>
</div>
答案 0 :(得分:1)
尝试
<div id="back" onclick="finddata(2)">Back</div>
将def
参数设置为1
以外的值,该$.get()
应在else
<{1}} finddata
语句中调用var data;
function finddata(def) {
if (def === 1) {
// do stuff
} else {
// if `data` defined
if (data) {
// do not do stuff here
}
// else call `.get()`
else {
var word = id.innerHTML;
$.get( "processor.php?query=" + word + "&def=" + def, function(data2) {
$("#results").html(data2);
$("#back").click(function(){
$("#results").html(data1);
});
});
}
}
}
$("#back").click(function() {
finddata(2)
})
修改,更新
public class SearchCredential
{
public string Employee { get; set; }
public string CostCenter { get; set; }
}
