javascript - Function didn't work with document.all -


can me solve problem

javascript code:

function checkall(pobj) {        var mcurrstatus;        mcurrstatus = pobj.checked;        var mobjlist; mobjlist = document.all["process"];        (x = 0; x <= 2; x++) {            var obj;           obj = mobjlist[x];           obj.checked = mcurrstatus;        }  } 

asp-classic code:

 response.write "<td nowrap><input type=checkbox name=process_1 "   response.write "/>box1</td>"   response.write "<td nowrap><input type=checkbox name=process_2 "   response.write "/>box2</td>"  

and selectall box :

response.write "<th align=left><input type=checkbox onclick=checkall(this)></th>" 

how select thoses boxes when click select box (it's seem function doesn't work) please me instead of giving me example... guy help~

updated:

i refer roland suggestion , make new function doesn't work idea?

function checkall() {

var eles = []; var len = elems.length; //var inputs = document.getelementsbytagname("input"); var elems = tab.getelementsbytagname("input"); (var = 0; < len; i++) {     if (elems[i].name.indexof('process_') == 0) {         eles.push(elems[i]);     } }  //var elems = tab.getelementsbytagname("input"); (var x = 0; x < len; x++) {     if (elems[x].type == "checkbox") {         elems[x].checked = true;     }   } 

}

this how can select , check checkboxes:

first find elements (this vanilla.js):

// find html elements have name containing value passed var find = function(name) {     // can optimize part bit (pass tag name)     var elements = document.getelementsbytagname("*");     var results = [];     for(var = 0; < elements.length; i++) {         var elementname = elements[i].name;         if(elementname !== undefined && elementname.indexof(name) != -1) {             results.push(elements[i]);                       }     }     return results; }; 

then how use "utility" function check all:

var checkall = function() {     var checkboxes = find("process");     for(var = 0; < checkboxes.length; i++) {         checkboxes[i].checked = true;     } }

as side note, bit here not valid html (you're missing quotes):

response.write "<td nowrap><input type=checkbox name=process_1 "  response.write "/>box1</td>"  

i beleive needs be:

response.write "<td nowrap><input type='checkbox' name='process_1' "  response.write "/>box1</td>"
