[英]return value from jquery modal dialog hat links to another page
我正在創建一個jQuery模式對話框並將其鏈接到另一個頁面中的表單,如下所示:
var $dialog = $("<div></div>")
.html('<iframe style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>')
.dialog({
autoOpen: false,
modal: true,
height: 400,
width: 300,
title: "Multiple HAWBs",
buttons: {
"Save": function() {
$( this ).dialog( "close" );
},
"Cancel": function() {
$( this ).dialog( "close" );
}
},
close: function() {}
});
$dialog.dialog('open');
});
在鏈接頁面上,我有一個元素,並且我試圖從對話框中讀取所選值到我的父頁面,我該怎么做?
如果iframe的來源是其他域,則不能這樣做。 在其他情況下,您可以通過向該元素添加ID來訪問其內容
<iframe id="myiframe" style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>'
然后簡單地
document.getElementById('myiframe').contentWindow.document
看看這是否是您需要的東西: 這里

$(document).ready(function(){
$(".click").on('click',function(){
myDialog();
});
});
function myDialog(){
var $dialog = $("<div></div>")
.html('<iframe style="border: 0px;" id="frame" src="view1.php" width="100%" height="100%"></iframe>')
.dialog({
autoOpen: false,
modal: true,
height: 400,
width: 300,
title: "Multiple HAWBs",
buttons: {
"Save": function() {
var data="";
var childrens= $($(document.getElementById('frame').contentWindow.document)[0].activeElement).children();//get allthe fields of dialog
childrens.each(function(index){
if(childrens[index].id == 'addme1'){
data=data+childrens[index].value;//this is just to show you the reading of content of dialog.
}
})
$( this ).empty();
$("#parent").html(data);
$( this ).dialog( "close" );
},
"Cancel": function() {
$( this ).dialog( "close" );
}
},
close: function() {
}
});
$dialog.dialog('open');
}
</script>

<div id="parent">i'll be changed using dialog data</div>
<button class="click">Open Dialog</button>
