How can I use Javascript to loop through HTML elements and remove inline attributes? -


i working online store platform doesn't provide full editing access html on page , looking vanilla js solution remove various inline styling can't remove directly.

i interested in reusable function such purpose, use type of capability on project later.

my solution involved creation of 2 dimensional array , 2 helper functions. hope else finds useful on 1 of projects:

step 1 - setup element/node list

the first part of fill application elements want work with. nested arrays have 2 values: css selector element in question, , boolean (true/false) flag indicate if element's children should have attributes removed.

var element_array = [     ['.selector', true],     ['.other-selector', false] ];

step 2: setup inline attribute array

the next step indicate html attributes want remove each element. each entered array:

var remove_attributes_array = [     'style',     'align',     'border',     'cellpadding',     'cellspacing',     'width',     'height' ];

step 3: setup helper functions

the helper functions perform logic of searching through elements , removing inline styles.

function 1: agnostize_element_styles(array);

this function loops through element_array variable (array literal step 1) , executes second function (which removes attributes). if 2nd array value true, element's children iterated on , inline attributes removed.

function source

function agnostize_element_styles(array) {     for(var = 0; < array.length; i++)     {         var element_list = document.queryselectorall(array[i][0]);          for(var = 0; < element_list.length; i++)         {             inline_html_attributes( element_list[i], remove_attributes_array );              if( array[i][1] === true && element_list[i].haschildnodes() )              {                 var child_nodes = element_list[i].queryselectorall('*');                  for(var = 0; < child_nodes.length; i++)                 {                     inline_html_attributes( child_nodes[i], remove_attributes_array );                 }             }         }     } }

function 2: inline_html_attributes(element);

this function accepts element argument, removes inline attributes specified in step 2's array variable.

function source:

function inline_html_attributes(element, attribute_array) {      for(var = 0; < attribute_array.length; i++)     {         element.removeattribute(attribute_array[i]);     } }

step 5: call function 1 using step 1 array

to make of work, run first function (agnostize_element_styles) passing in 2 dimensional array step 1 argument:

agnostize_element_styles(element_array);

var element_array = [     ['.selector', true],     ['.other-selector', false] ];  var remove_attributes_array = [     'style',     'align',     'border',     'cellpadding',     'cellspacing',     'width',     'height' ];  function agnostize_element_styles(array) {     for(var = 0; < array.length; i++)     {         var element_list = document.queryselectorall(array[i][0]);          for(var = 0; < element_list.length; i++)         {             inline_html_attributes( element_list[i], remove_attributes_array );              if( array[i][1] === true && element_list[i].haschildnodes() )              {                 var child_nodes = element_list[i].queryselectorall('*');                  for(var = 0; < child_nodes.length; i++)                 {                     inline_html_attributes( child_nodes[i], remove_attributes_array );                 }             }         }     } }  function inline_html_attributes(element, attribute_array) {      for(var = 0; < attribute_array.length; i++)     {         element.removeattribute(attribute_array[i]);     } }  agnostize_element_styles(element_array);
