在dynamics crm中自定义控件

我通过在电话字段上放置一些html(div和锚)解决了这个问题。下面的代码在给定字段的文本框末尾放置一个电话图标。

crmForm.ApplyClickToDial= function(field, href){
var phoneField = field;
phoneField.style.position = "relative";

var imgAnchor = document.createElement("a");
phoneField.appendChild(imgAnchor);

imgAnchor.href=href;
imgAnchor.style.position = "absolute";
imgAnchor.style.right = ".5em";
imgAnchor.style.top=".5em";

var image = document.createElement("img");
image.src ="/_imgs/ico_16_4210.gif";
imgAnchor.appendChild(image);
}

var mobileNumber = crmForm.all.mobilephone.DataValue;
crmForm.ApplyClickToDial(crmForm.all.mobilephone_d, "http://callphone/" + mobileNumber );  /*  the "_d"  represents the control's encompassing td element*/
