DOM正在按顺序创建HTML元素

我正在尝试使用DOM动态创建HTML元素。

除了它们出现乱序之外,所有元素都被绘制出来。

例如,创建和附加元素的函数如下所示:

function inputForms(goal){
if(goal=="fatloss"){
    // remove any form previous created
    $("#"+"input_child").remove();
    // create new form section
    createDiv("input_parent","input_child");
    // create form elements
    Label("input_parent","curr_act_label","curr_act_lvl","Current Activity Level:");
    selectInputElement("input_child","curr_act_lvl");
    selectOption("curr_act_lvl","Please Select Your Current Activity Level...", "none");
    selectOption("curr_act_lvl","No Exercise or Desk Job", "1.25");
    selectOption("curr_act_lvl","Little Daily Activity or Light Exercise 1-3 Days Weekly", "1.35");
    selectOption("curr_act_lvl","Moderately Active Lifestyle or Moderate Exercise 3-5 Days Weekly", "1.55");
    selectOption("curr_act_lvl","Physically Demanding Lifestyle or Hard Exercise 6-7 Days Weekly", "1.75");
    selectOption("curr_act_lvl","Hardcore Lifestyle 24/7", "1.95");

    Label("input_parent","curr_bodyfat_label","curr_bodyfat_input","Current Bodyfat:");
    InputField("input_parent","curr_bodyfat_input","text",5,3)

    Label("input_parent","curr_weight_label","curr_weight_input","Current Weight:");
    InputField("input_parent","curr_weight_input","text",5,3)

    Label("input_parent","meals_label","meals_input","Daily Meals:");
    InputField("input_parent","meals_input","text",5,1)

    Label("input_parent","goal_bf_pct_label","curr_weight_input","Current Weight:");
    InputField("input_parent","curr_weight_input","text",5,3)

    Label("input_parent","time_label","time_input","Weeks To Goal:");
    InputField("input_parent","time_input","text",5,2)

    Label("input_parent","deficit_label","deficit_select","Decifict By:");
    selectInputElement("input_child","deficit_select");
    selectOption("deficit_select","Please Select a deficit Method:", "none");
    selectOption("deficit_select","Burn With Exercise", "burn");
    selectOption("deficit_select","Fasting/Calorie Restriction Without Exercise", "starve");

结果是尽管在它们之前创建了标签元素,但两个“select”元素出现在最顶层。

所以最终会像这样呈现:

选择元素

选择元素

标签< ---属于第一个选择元素

标签

inputfield

标签

输入字段

标签

输入字段

标签

标签< - 属于第二个输入字段

它应该看起来更像这样(我为重点组织添加了空格):

标签 选择元素

标签 inputfield

标签 输入字段

标签 输入字段

标签 选择元素

以下是我创建这些元素的功能:

function createDiv(section_id, div_id){
section=document.getElementById(section_id);

div=document.createElement("div");
div.setAttribute("id",div_id);

section.appendChild(div);

}

function selectInputElement(section_id,input_select_id){
section=document.getElementById(section_id);

select_element=document.createElement("select");
select_element.setAttribute("id",input_select_id);


section.appendChild(select_element);
}

function selectOption(input_select_id,option_text,option_value){
element=document.getElementById(input_select_id);

option=document.createElement("OPTION");
text=document.createTextNode(option_text);
option.setAttribute("value",option_value);
option.appendChild(text);

element.appendChild(option);
}


function InputField(section_id,input_id,element_type,size,length){

section=document.getElementById(section_id);

input_field=document.createElement("input");
input_field.setAttribute("id",input_id);
input_field.setAttribute("type",element_type);
input_field.setAttribute("maxlength",size);
input_field.setAttribute("size",length);
section.appendChild(input_field);

}

function Label(section_id,label_id,label_for,label_text){
section=document.getElementById(section_id);

label=document.createElement("label");
label.setAttribute("id",label_id);
label.setAttribute("for",label_for);
label_txt=document.createTextNode(label_text);
label.appendChild(label_txt);   

section.appendChild(label);
}

答案 0 :(得分:1)

您将select元素附加到与label(和其他)元素不同的容器中。

将所有这些内容附加到孩子身上使其按预期工作。

IMO,您的API可以采用单个对象参数,因此您可以标记值。
