I am trying to select folder content.This folder contain images when I am selecting that folder it will select all content.plus it is taking img src undefind. so I need to remove that how can I remove if src is undefined using asp.net c#
<div id="cell" class="box2">
<a href="undefined">
<img width="260px" height="135px" src="undefined"
alt=""
style="box-shadow: 1px 2px 2px #BDBDBD;
border: 1px solid #D1D1D1;">
</img>
</a>
</div>
Code behind file:
protected void chbindustry_SelectedIndexChanged(object sender, EventArgs e)
{
if (result == false)
{
string[] subdirectoryEntries = Directory.GetDirectories(Server.MapPath("BusinessCards"));
string f;
string[] ss;
string side = chklist.SelectedValue;// RadioButtonList1.SelectedValue;
foreach (ListItem li in chbindustry.Items)
{
if (li.Selected)
{
ss = li.Text.Split('(');
f = Server.MapPath("BusinessCards").ToString() + "\\" + ss[0];
int c = f.Count();
DirectoryInfo d = new DirectoryInfo(f);
int len = d.GetFiles().Length;
for (int i = 1; i <= d.GetFiles().Length / 3; i++)
{
Page.ClientScript.RegisterArrayDeclaration("ImgPaths", "'" + "BusinessCards/" + f.Remove(0, f.LastIndexOf('\\') + 1) + "/" + i + ".jpg'");
Page.ClientScript.RegisterArrayDeclaration("refs", "'" + "DesignBCs.aspx?img=BusinessCards/" + f.Remove(0, f.LastIndexOf('\\') + 1) + "/" + i + "&Side=" + side + "'");
}
}
}
}
result = true;
}
Dynamically creating div:
<script type="text/jscript">
$(document).ready(function () {
for (var i = 0; i < ImgPaths.length; i = i + 3) {
var rowdiv = '<div id="row">';
rowdiv = rowdiv + ' <div id="cell" class="box2">';
rowdiv = rowdiv + ' <a href="' + refs[i] + '"><img width="260px" style="box-shadow: 1px 2px 2px #BDBDBD; border: 1px solid #D1D1D1;" height="135px" alt="" src="' + ImgPaths[i] + '"></img></a> ';
rowdiv = rowdiv + ' </div>';
rowdiv = rowdiv + ' <div id="cell" class="box2">';
rowdiv = rowdiv + ' <a href="' + refs[i + 1] + '"><img width="260px" style="box-shadow: 1px 2px 2px #BDBDBD; border: 1px solid #D1D1D1;" height="135px" alt="" src="' + ImgPaths[i + 1] + '"></img></a>';
rowdiv = rowdiv + '</div>';
rowdiv = rowdiv + ' <div id="cell" class="box2">';
rowdiv = rowdiv + ' <a href="' + refs[i + 2] + '"><img width="260px" style="box-shadow: 1px 2px 2px #BDBDBD; border: 1px solid #D1D1D1;" height="135px" alt="" src="' + ImgPaths[i + 2] + '"></img></a>';
rowdiv = rowdiv + '</div>';
rowdiv = rowdiv + '</div>';
$("#table").append(rowdiv);
}
});
</script>
Handle the onError event for the image to call JavaScript function which will remove the div:
function imgError(divid) {
document.getElementById(divid).style.display = 'none';
return true;
}
<img src="image.png" onerror="imgError(divid);"/>
you need to pass div id to function which you want to hide.
