</select>
<select name="salut-1358937582000-OK">

...
In javascript, I want to get all select/option list which started by "salut-". For theses list, i want to compare his name and his selected value.
在javascript中，我想获取以“salut-”开头的所有选择/选项列表。对于论文列表，我想比较他的名字和他选择的值。
I know it is possible in jQuery but can't use jquery, only javascript (JSNI with GWT exactly).

var selects = document.getElementsByTagName('select');
var sel;
var relevantSelects = [];
for(var z=0; z<selects.length; z++){
sel = selects[z];
if(sel.name.indexOf('salut-') === 0){
relevantSelects.push(sel);
}
}
console.log(relevantSelects);

You can use the getElementsByTagNamefunction to get each SELECTname, for example:
您可以使用getElementsByTagName函数来获取每个SELECT名称，例如：
var e = document.getElementsByTagName("select");
for (var i = 0; i < e.length; i++){
var name = e[i].getAttribute("name");
}
Then you can use the following code to get each OPTIONfor the SELECT, to do any necessary comparisons:
然后你可以使用下面的代码来获得每OPTION对SELECT，做任何必要的比较：
var options = e[i].getElementsByTagName("option")

var ModalListInputs =document.getElementById("checks")
var arrayInput = ModalListInputs.getElementsByTagName("input");
//console.log(arrayInput);
for(var x=0; x <= arrayInput.length-1; x++){
if(arrayInput[x].getAttribute("type")=="checkbox" && arrayInput[x].checked ==true){
console.log(arrayInput[x].value);
}
}
