javascript - Auto add an anchor tag if currenttext === "@WebSecurity.CurrentUserName +<br>+ 'CP'" -


i'm trying add anchor in cell of specific table according text. here got far...

for (var d = 0, max = alltablecells.length; d < max; d++) {     var node = alltablecells[d];     var currenttext = node.childnodes[0].nodevalue;      if (currenttext === "@websecurity.currentusername + 'text'")         node.childnodes[0].nodevalue = '<a name="cp"></a>'     } }

the main issue here seems 2 lines...

if (currenttext === "@websecurity.currentusername + 'text'")     node.childnodes[0].nodevalue = '<a name="cp"></a>'

if me, nice... thank you

here complete script of page: var alltablecells = document.getelementsbytagname("td");

for (var = 0, max = alltablecells.length; < max; i++) {     var node = alltablecells[i];       var currenttext = node.childnodes[0].nodevalue;       if (currenttext === "@websecurity.currentusername")         node.style.color = "blue";          node.style.border = "solid"         }      (var c = 0, max = alltablecells.length; c < max; c++) {     var node = alltablecells[c];     var currenttext = node.childnodes[0].nodevalue;       if (currenttext === "none")         node.style.color = "black";     node.style.border = "solid" }  var d, max, node, nodes, currenttext, anchor; (d = 0, max = alltablecells.length; d < max; d++) { node = alltablecells[d]; nodes = node.childnodes; currenttext = nodes[nodes.length - 1].nodevalue;     if (@websecurity.currentusername === nodes[0].nodevalue && currenttext === 'cp') {     anchor = document.createelement('a');     anchor.name = 'cp';     alltablecells[d].insertbefore(anchor, nodes[0]); }

}

</script>

a cell <td>bob<br>text random<br>cp</td> contains childnodes below:

nodes = td.childnodes; nodes[0] === bob nodes[1] === br element nodes[2] === text random nodes[3] === br element nodes[4] === cp

notice, if </td> not on same line cp, there nodes[5] === empty text node.

if text want check (said cp in comment) in last node, need change code this:

var d, max, node, nodes, currenttext, currentuser, anchor; (d = 0, max = alltablecells.length; d < max; d++) {     node = alltablecells[d];     nodes = node.childnodes;     currentuser = parent.@websecurity.currentusername;     currenttext = nodes[nodes.length - 1].nodevalue;         if (currentuser === nodes[0].nodevalue && currenttext === 'cp') {         anchor = document.createelement('a');         anchor.name = 'cp';         alltablecells[d].insertbefore(anchor, nodes[0]);     } }

a simplified demo @ jsfiddle.

edit

in comments you've told code executed in iframe. assume @websecurity.currentusername defined in main window. make sure it's global variable in main window, can use edited snippet above.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
