The example in this article describes how to implement JS to disable all controls on the page. Share it with everyone for your reference, the details are as follows:
Using the characteristics of page elements, all elements can be captured.
function DisableElements(container,blnHidenButton) { if (!container) return; var aEle; if (navigator.appName =="Microsoft Internet Explorer") //IE { for (var i=0;i<container.all.length;i++) { aEle = container.all[i]; tagName = aEle.tagName.toUpperCase(); if ((tagName=="SELECT")) { aEle.disabled = true; if(tagName=="BUTTON" && blnHidenButton) { //aEle.style.display = "none";//对button不做处理 } } else if (tagName=="INPUT") { if (aEle.type.toUpperCase()!="HIDDEN") { if (aEle.type.toUpperCase()=="TEXT") { ReadonlyText(aEle); } else if (aEle.type.toUpperCase()=="BUTTON") { //do nothing; } else { aEle.disabled = true; } } if((aEle.type.toUpperCase()=="BUTTON"||aEle.type.toUpperCase()=="SUBMIT") && blnHidenButton) { //aEle.style.display = "none";//对button不处理 } } else if (tagName=="TEXTAREA") { ReadonlyText(aEle); } } } else//非IE浏览器 { var aEle = container.getElementsByTagName("select"); for (var i=0;i< aEle.length;i++) { aEle[i].disabled = true; } aEle = container.getElementsByTagName("button"); for (var i=0;i< aEle.length;i++) { aEle[i].disabled = true; } aEle = container.getElementsByTagName("textarea"); for (var i=0;i< aEle.length;i++) { ReadonlyText(aEle[i]); } aEle = container.getElementsByTagName("input"); for (var i=0;i< aEle.length;i++) { if (aEle[i].type.toUpperCase()!="HIDDEN") { if (aEle[i].type.toUpperCase()=="TEXT") { ReadonlyText(aEle[i]); } else { aEle[i].disabled = true; } } if((aEle[i].type.toUpperCase()=="BUTTON"||aEle[i].type.toUpperCase()=="SUBMIT")&&blnHidenButton) { aEle[i].style.display = "none"; } } } } function ReadonlyText(objText) { if (objText){ //objText.style.backgroundColor = "menu"; objText.style.background = "#E6E6E6"; //objText.style.color = "black"; objText.readOnly=true; } }
The effect is very good. I have kept all the buttons here. If you want to disable the buttons, you can remove the comments.
Calling code:
Suppose there is a form named formeditor. The calling method is as follows:
var myForm=document.forms["formEditor"]; DisableElements(myForm,'true');
